[RX] Header error detected (0x0020) - corrupted header, restoring RX mode

[jbalki]

Can seem to get the repeater to see any other devices, I have confirmed both are using the same RF settings, and the companion device works fine.

Hardware:
Raspberry PI 4
Waveshare SX1262 LoraWAN HAT (SKU: 22002)

Could it be simple as the Waveshare hat I have its not supported?

I am running the same setup but when purchasing I did note that there are a couple of different ones. I think the main difference was either the frequencies and GPS but worth checking Mine has worked amazingly well. Just want to get the MQTT bit working :)Thanks On 18 Feb 2026, at 06:06, jbalki ***@***.***> wrote:jbalki created an issue (rightup/pyMC_Repeater#95) Can seem to get the repeater to see any other devices, I have confirmed both are using the same RF settings, and the companion device works fine.

Thank you, mine is the 915 frequency, correct for my location and no GPS.

[jbalki]

Seems that the issue exists on Australia (Narrow) frequency, when i move it to Australia frequency (and change settings on my companion device) it works fine.

In short:
916.575MHz SF7/BW62.5/CR8 fails with header errors,
915.800MHz SF10/BW250/CR5 works

I have also tried the US/Canada settings (BW62.5) and that also produces the same error. Looks like this could potentially be an issue with the 62.5 bandwidth.

Have you tried the dev branch? there have been some changes in ref to this.

Im currently running the dev branch, and still receive the same error.

Do you mind trying the feat/newRadios sorry I just realised I pushed the fix to that branch not dev.

I changed to the feat/newRadios. Seems a step in the right direction. I have had a flood message forwarded but still a lot of the same errors in the logs
