v22.46.0 & v22.20.0 not working with TBeam v1.0 on 33cm #228

I tried updating my TBeams today and discovered an odd behavior .

I have two pairs of TBeams: One pair on 70cm and another pair on 33cm: I-Gate v22.14.0 and Tracker v22.19.0 - Everything works fine on both pairs.

Updated both pairs to: I-Gate v22.46.0 - 33cm doesn't working

Downgraded the I-Gate on the 33cm I-Gate back to v22.14.0 - Works fine.

Updated the I-Gate to v22.20.0 - Doesn't work.

Again, downgraded the I-Gate on the 33cm back to v22.14.0 - Works fine.

This is the problem I am seeing. The I-Gate doesn't receive the Tracker's beacons. I am using the exact same JSON configuration across the different versions. The I-Gate will log on to the APRS servers and report it's status.

During the upgrade/downgrade process. I 'erased flash' and 'clean' the build. I also removed the battery and USB power to ensure I was starting with a completely blank TBeam.

Hi Doug,

I have an iGate/Digi up for LoRa APRS on 70cm to complement 2m and am just starting to set up for 33cm. I saw you have a couple nodes up already advertising 33cm operation. There seems to be some consensus for 70cm LoRa APRS, but I did not see any clear standards for 33cm except to copy the non-ham stuff. What frequency and LoRa config are you running? Although our coverage is far apart, maybe if we follow/create a standard, anyone in between can follow suit.

Once I get this up on the Heltec, I will try the TBeam. I already have APRS loaded on a T-Echo, but won't know if it is working right until I get the next one loaded. I will let you (and Peter) know if I find any bugs.

I set my frequency to 915.775Mhz. As far as the config. Everything is the same as 70cm. I wanted to keep it simple for converting from one band to another.

Good luck!! 73
