Razberry bricked?
Posted: 18 May 2021 09:30
Hi,
I changed raspberry casing and in that process removed razberry board. Also once in mistake powered raspberry without board attached back.
Then I powered back off, attached board back and started again. But now z-way not working anymore. I don't have any devices visible and then I found from logs that communication with razberry fails.
1. I took a look of hardware troubheshoot steps on https://z-wave.me/support/hardware-problems/
It seems that when powering pi, one led on razberry board goes on for one second.
But z-wave is not able to communicate with board, symptoms are just like descriped and ends to:
"Can not start Z-Wave binding: Error: Bad data – communication failed"
Unpowering does not help.
2. Then I found (https://forum.z-wave.me/viewtopic.php?t=23019) How to test Razberry:
killall z-way-server
cat < /dev/ttyAMA0 &
echo -en "\x01\x03\x00\x15\xe9" > /dev/ttyAMA0
and after that echo command I'm getting no any response (no failure or no answer, nothing).
I think I have this model (https://z-wave.me/products/razberry/razberry-revisions/):
Z-Wave Plus
5th gen chip
ZM5202
Does this mean, that board is now broken or is there something I could still try?
