[OpenThread Border Router] RCP failure detected, failure to recover

[jmzg93]

Describe the issue you are experiencing

Hello.
I’m trying to configure an SLZB-MR4U and create a Matter network with OTBR, but when I set it up exactly as shown in the official tutorials and device documentation, I keep getting this error:

52d.10:03:11.103 [W] P-RadioSpinel-: Wait for response timeout
52d.10:03:11.103 [W] P-RadioSpinel-: RCP failure detected
52d.10:03:11.103 [W] P-RadioSpinel-: Trying to recover (1/2)
52d.10:03:11.168 [W] P-HdlcIntface-: Error decoding hdlc frame: Parse

I’ve contacted the device manufacturer, and they told me it might be an OTBR issue.
Could you please help me?
Thanks in advance.

Same issue for me, even if you connect it via USB

[rrhernandez]

I had the same issue, Reflash the EFR32MG26 chip in the SLZB-MR4 and everything will work again.

Gave this a try already and again, but no chance - still the same issue. Is your config the same like from @jmzg93 ? Which firmware is flashed on your device and do you also use the SLZB-MR4(U)?

Device Info

[rrhernandez]

The same config but SLZB-MR4 (not U)
Firmware type: Matter-over-Thread
Revision: 20250703

[jsfr]

I can confirm the same issue also on the SLZB-MR4U. It seems there's some difference causing that particular device to fail. I've also tried reflashing multiple times to no avail.

[StelardActek]

SMLight support gave me a beta OS firmware that fixed the issue for me. They're planning on releasing it properly soon, apparently. :)

[geoemm7]

I am getting the same error "00:00:42.828 [W] P-HdlcIntface-: Error decoding hdlc frame: Parse" on my SLZB-MR1U hwile trying to attach a tado to my OTBR in HA OS

[mwLabs-eu]

Today, v3.0.9 of SLZB OS was released, which fixed the issue for me. I flashed the OS to the newest version, but also the EFR32MG26 once more. Now i was able to successful start OTBR and connect a matter device to HA.

[aavdberg]

@mwLabs-eu when doing firmware update check and looking at site there is no 3.0.9 firmware available

https://smlight.tech/flasher/#SLZB-06U-MRxU

When going to download there it's is, only main page is not yet updated

[aavdberg]

@mwLabs-eu even 3.1.0 is available

I believe this PR may help OTBR recover from RCP failures better: #4220
