CC2531 based router (firmware)

I’ve replaced my old coordinator hardware with CC2530 with an external antenna and therefore one of CC2531 was not used.

The guys on GitHub asked me to make a router firmware for СС2531 too. I’ve spent some time and prepared 3 variants:

  1. CC2531-router.hex – just a router, without diagnostics and a USB serial port.
  2. CC2531-router-diag.hex – a router with diagnostic reports and without a USB serial port.
  3. CC2531-router-diag-usb.hex – a router with diagnostic reports and a USB serial port. The firmware dumps diagnostic reports to the serial port too.

CC2530 based Zigbee coordinator and router

Introduction

My smart home infrastructure contains several Xiaomi humidity/temperature and door sensors. I’ve used these sensors with the corresponding Xiaomi gateway. The gateway was connected with my BananaPi M2U and Pimatic. But my home is long and tall. One gateway does not cover all rooms and therefore far sensors disappear periodically.

I’ve googled and found I can use Xiaomi sockets (Zigbee edition) like Zigbee routers. This socket is less expensive than a new gateway and it has a smaller size. I’ve purchased tow sockets and used it about a month. This socket has a big problem (from my point of view). It can go into the deep sleep mode and cannot forward data packets from sensors.

There are no more results.
