Selectable Baudrate: 460800 for Corrdinators

Selectable Baudrate: 460800 for Corrdinators

I would suggest to use one of the values already available. There is no advantage in a faster baud rate.

Hi Chris,

thanks for that but if the Firmware only supports 460800 in case of HW Flow control?

As per above; community firmware builders are now starting to provide firmware images with different baud rate speeds, and a few community testers are at least claiming that 230400 baud rate speed gives them better results in very large Zigbee networks.

FYI tip for devs, darkxst is providing prebuild cutting-edge firmware for most common EFR32MGxx adapters with different speeds:

https://github.com/darkxst/silabs-firmware-builder/tree/manifestjs-SL/firmware_builds

ncp-uart-hw- = EZSP mode (pure EmberZnet Zigbee NCP).
rcp-uart-802154- = RCP mode for MultiPAN/multiprotocol (requires Silicon Labs EZSP and/or OpenThread daemon on the host).
ot-rcp- = OpenThread Only (Thread Spinel mode).

Note! That hw in the files name does not currently mean hardware flow control as that is hardcoded in the patches today.

For example, check out firmware for Sonoff ZBDongle-E (by ITead) hardware which has latest NCP images in different buad rate:

Web Flasher - Flash newer Silabs EFR32 adapters directly from your browser (only Chrome and Edge supported) -> SL Web Flasher

Read this blog post for more details and instructions for using RCP Multi-PAN firmware (with Silabs Multiprotocol Addon for HA).

Tip; The manifestjs-SL branch in darkxst's silabs-firmware-builder repo also allow you to build same firmware images yourself:

PS: Some other Zigbee gateway solutions have an "Auto" mode where it probe to test connecting, starting at higher speed & HW.
