The premium version has the same features as the free version, plus:

  • It allows you to define 16 GPIO inputs or outputs (for example, you may define 8 GPIO outputs and 8 external sensors, or 16 GPIO outputs for relays).
  • It allows you to create battery-powered DIY devices with effective power management.
  • PCF8583 counter, PCA9685 multi-channel PWM.
  • 5 hardware built-in PWM apart from of 4 PWM in the free version.
  • Hardware PWM with low frequencies.
  • LED features: WS2812B strips or multi-channel color LED lamps.
  • DS3221 Real-time clock.
  • CRON scheduler.

I plan to add new features and sensor types to the premium version.

I am using firmware version 1.7.2.0 on an CC2530 in PSM mode. It is configured to poll for queued commands every 5 seconds, and I have disabled resetting of the device by a power on/off cycle. I am using zigbee2mqtt on home assistant as coordinator. Everything works as expected for a couple of days but eventually the device will stop reporting the sensor values and stops responding to commands. Power cycling it does not help but if I read the flash using the flash programmer and compare it to the original file it reports β€œVerify against file OK”. If I then read the flash into a file and program the chip with this exact file, remove the device from zigbe2mqtt and repair it, it works again for a couple of days until it fails again eventually. I do not know where to look next for possible problems. Do you have an idea?

How do I know the IEEE of the E72-2G4M20S1E module? Connected via J-Link V9 (J-Link itself was normally installed and after the launch of J-link Commander, the firmware of the programmer was updated), the UniFlash module does not see. How to firmware this module? Paid for 3 devices.

Flash Programmer v2 defines the j-link programmer, but I did not find how to enable JTAG mode. I already did on E18 MS1-PCB modules, but I would like to use E72.

I use the PSM function with a CC2530 to control a battery powered device. Is there a way to pulse a pin once on boot up of the device? I would need this to initialize an SR latch with which the CC2530 controls power to the main part of the project.

    I can only offer a workaround. You can add a bistable relay (remember state: off, restore last state: off). This relay type has two signals: ON and OFF. You can use any virtual pin for the ON signal. The firmware will send a short OFF pulse when the firmware starts.

Hi!
I need a device for separate control of 8 LED tapes based on CC2652P. The description says that only 5 can be used (in the premium version), but the configurator does not issue an error if I make 8 outputs with hardware PWM. Will this configuration work properly?

    No, this configuration will not work. You can only use 5 PWM channels. I would recommend splitting this device to two independent devices or use an external PWM controller like PCA9685 (https://ptvo.info/zigbee-configurable-firmware-features/external-sensors/16-channel-zigbee-pwm-controller-pca9685/)

          The link describing the settings for PCA9685 uses 7 PCA9685 PWM outputs, you write about 8. You can take a screenshot for an example with 8 PCA9685 PWM outputs enabled. And can I add 2 DS18B20 temperature sensors to this? Is the limit on the number of PWM outputs for a module on the CC2652P hardware or software?

Hi, I have a temperature sensor running on a CC2530 module, bought the PSM licence for it. It works fine but I would like to know if the HTU21D sensor is in sleep mode between the reports.
Datasheet say’s it’s sleep current is 0,02 uA and when measuring it’s 450 uA, that makes a big difference in battery life.
Thanks.

Am I reading the premium licensing correctly, that I need a separate license for each device I deploy the firmware to? Like If I’m making a custom zigbee sensor for my home, and I intend to flash/deploy 10 of these, I need to pay $3.95 for EACH device? Please tell me I’m reading that wrong. That pricing model is astronomically expensive.

Hello, I am very happy to see, that you have managed to build PSM. I reckon, also the pricing is fair to get started. My question: Can I build a device that sleeps, will be woken up by a radio based command, controls a gpio and falls back to sleep. In other simple words, a remotly controlled “relais”. Is this possible with 4uAmps standby? Thanks for your input

    Hello,

    Please, note it is not true sleep because the device should wake up, enable radio and check for commands.
    You should enable the “Poll for queued commands” option on the “Expert” tab. Power consumption depends on the interval. Average consumption will be more than 4uA.

      Makes sense. Can the HW “queue”/receive commands while deep sleeping, or only when awake (I assume around 20mA)? In other words, would I miss a command, while deep sleeping?
      Would you mind, putting up a screenhot of the “Expert” tab?

        The device cannot receive anything in the sleep mode because the radio is off. You should not miss a command because a coordinator or router should hold these commands for some time (note, some routers do not support this mode).

          Understood. So how is e.g. the IKEA FYRTUR blind achieving this? It runs on 2 18560 Cells (~6Ah) almost 160 days with 2 motor cycles of ~15sec a day (maybe 4-5Ah). There is not much energy left for a 24×7 monitoring (say 0,5mA avg.). That would be a ratio of 1:100 with 4uA sleep. If I press the zigbee remote, it feels it reacts instantaniously. I guess less then 200ms delay. Reading your post, I would have to poll with this frequency (4-5times per second). Could I sleep so short inbetween to get an avg consumption of 0,5 mA?. Wat would be the timings for wake-up? Do you have data for this? Is there a different mode/profile in ZigBee to achieve this? Thanks heaps, Dieter

Would I be in the right ballpark, if I wake up for queue reading every 1 sec.–> 5 x as often. The consumption would be in the order of 5 x 30uA = 150uA for 120s or 75uA/sec.

Interested in PSM but have a couple questions. If we don’t have an external interrupt is there a way to have the device sleep for say 1 hour, take a reading, send data, and then sleep again? Also have a question about using GPIO for power. If I pull one of the 20ma GPIO to high to provide power to a sensor can this set the GPIO to low before sleeping to save power?

I wrote earlier and mentioned the sleep low-power mode requirement. You have now added it and turned it into a commercial business model. Congratulations. I will contact you directly later for the high volume production regarding the price. But first, I want to quickly produce a prototype evk and test and measure it. I could not see the memory requirement for firmware, how much flash size is required minimum. I will design for CC2530Fxxx as per the requirement. Also, do you have any notes to warn before drawing?

I’ve been waiting for the ability to make batter powered devices. I’m going to guess that there is some kind of serial number in the cc2530 which you can limit the use of a limit the use of that version of your firmware. Assuming this is how it will function, will I be able to massively change the function of this one unit under the original license. lets assume i’m dropping one senor for a newer sensor. And you now deed to add several voltage measurements.
This all has changed the function of the device but it is still using the original2530 board.

Am I on the right track here?

      What about P21, P22? Do you know any problems with using those as input/output?
      I’m having trouble with software/hardware that I don’t know the reason for. Using the MS1PA1 module (and not using P10, P11) CC2530 keeps restarting after a few seconds – but when I use any of the inputs (which causes the output toggle) the problem disappears. It looks like it’s rebooting until the first input is received. After turning it off / on, the problem returns.

      P.S. Any bigger discount on 20 licenses?

        There are no problems with P21, P22. Please, try to disable Input 1.

Hi

I have developed a home automation device based on the Zwave Z-Uno module, that is very easy to program, also for a hardware engineer as me πŸ˜‰
I found you firmware here for the Zigbee CC2530 circuit.
I want to mature my product for production, so it is not for DIY use.
I want to ask you some question, if you are interested in develop and supplying firmware for us, if we change to CC2530 series chips.
We are not able to make software for Zigbee communication, only for the application on top, we are not software engineers.
If interested, please reply to my email, and I will describe the project.

I want to build battery powered impulse counter (for electric consuption based on blinking LED) – do I need premium version for it? What is difference in power menagment in free vs premium version?

    The free version does not use power management and consumes about 8-28 mA. The premium version has the power-saving mode and consumes about 4 uA in the sleep mode. If your impulses are frequent, you don’t need the power-saving mode because the chip never sleeps.

      OK, thanks for that information… So I see that my device will last on planned battery (CR2032) just one day if I calculate it right… Impulse frequency is 6400 impulses for 1kWh… Typically in my consumption about 1 impulse per second… I think I need to plan bigger battery πŸ™‚

        I think you can use a constant power source if you calculate electrical energy.

          Unfortunately no… All in box is sealed, only impulse LED is visible, no possibility to connect to power source there… One more question – if I’ll use paid version with PSM and disable “wait for command” feature it should wake just when impulse received and sleeps immediately after? And it will wake each 60s to send report? If yes – it maybe can be acceptable with some bigger batteries than CR2032…

Maybe some (even one-time) discount for folks that donated you before? πŸ™‚

While I do love Your firmware, highly appreciate Your hard work and time invested into this product, and I also recommend your firmware many times on my local community; 7€ price tag per device is little bit too high for me, personally. (I use only 1-2 inputs/outputs and that’s it, but I would want to try out the power saving feature.)
However, I’ve donated you to before and even suggested using Buy Me A Coffee πŸ™‚

Maybe there’s a potential to provide demo mode (just to test out features and compatibility)? E.g. firmware that will work for only one week, or demo configurator with access to the premium features, but with limit of 1-2 features to be used at once.

    Hi!
    Yes, of course. I’ve sent you a key via email.

Can I use your project commercially?

    You can use my firmware commercially. But keep in mind, I can only provide limited support, and the firmware provided “AS-IS.”

Hi

How do you plan to manage the breakdowns?
This is DIY. During tests I destroyed 3 x IC E18-MS1-PCB.
I think you should plan in Premium an unlimited version in order to be able to replace the ICs destroyed during prototyping or handling error.

    Sorry, but I cannot manage breakdowns. You’ll lose a license for that device. Unfortunately, I don’t see a way to control an unlimited license too. Could you offer your variant?

200 Russian rubles is too expensive. It is easier then to buy the final device.

    Yes, of course. Any DIY will be more expensive than a mass-device because you make your personal effort on it. I suppose, your time costs more. Or you may compile your firmware yourself. There are many examples on the web.

    I think there is no comparable solution on the mass market. Besides, the prices are quite reasonable in my opinion. Note that the volume of potential sales is a limited but non-trivial amount of work done.

      Thank you :). I’ve started this project as a hobby. I hope, it may help more people.
