I have a LilyGo T3_V1.6.1 20210104.

I am trying to update the latest firmware V3.1.4.1, and I get the following error when I receive a beacon packet:
[13:16:23]Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled.

I've tried the upgrade, and the fresh install. This also happens for v3.1.2, v3.1.3, and 3.1.4. If I install 3.0.1 it receives packets with no issues. However when I connect via Network KISS TNC from PinPoint APRS, It only decodes the Callsign and not the Callsign & SSID. So instead of WA0DE-10, I get WA0DE.

Thank you very much!

Hi,

it seems you are experiencing two errors mixed.

  1. you should have a valid callsign (Tactical Callsigns are not validated at this moment and should be implemented in the future)
  2. this could be blocking all the decoding and connection to the TNC

please test it with a valid callsign and see if this solves all

Hi,

I have a similar problem.
With version 3.0, the ‘panic’ error disappears.

Tomorrow I will post the output at the time of the error, to see if that gives us more clues.
In my case, I have configured my call sign, but I am still getting the error.

Best regards.

I've tested with a valid callsign and still have the same issue. If I connect to a WAP, then it doesn't reboot when it receives a packet. And it still doesn't send anything to PinPoint APRS when connected as a Serial TNC.

I'm confused - what is invalid about his callsign? From his own comment

So instead of WA0DE-10, I get WA0DE

I see WA0DE and WA0DE-10, both valid calls, neither appear tactical.

Can you explain more?
