@jpgimenez
Which product are you trying to communicate to? Which firmware?
It seems it's responding, but doesn't recognize the frames, sent by our software

@NilsBohr not sure, I buy the shield more than 3 years ago, and is the first time that I try an upgrade... home-assistant reports this:

@jpgimenez
Noted, will check the utility with older version of the firmware.
Will get back to you

This is the board:

A workaround could try https://github.com/walthowd/husbzb-firmware/ Docker image as it contains a fork/modified Elelabs script.

But note that will need another firmware image for that older EM357 "Ember" series of Silicon Labs MCU hardware chip, see ex:

https://github.com/grobasoz/zigbee-firmware

PS: Understand that Silabs EmberZNet 6.7.10.x (latest = 6.7.10.0) is last release for EM35xx/EM35x as hardware is now end-of-life.

#19

grobasoz/zigbee-firmware#17

walthowd/husbzb-firmware#36

PPS: Remember that you may need to reconfigure the serial baud rate speed from 57600 to 115200 if changed in firmware.
