v1.1.7 - possible GPS related regression on tbeam-Modle

[a-f-G-U-C]

Description After upgrading device firmware from v1.1.6 to v1.1.7 on a tbeam1.1-M8N-SX1262 ("Modle"), the standalone location broadcast feature appears to have stopped working. Downgrading to 1.1.6 fixes the problem.

To Reproduce Steps to reproduce the behavior:

0. connect tbeam board to USB
1. upload firmware-1.1.6.bin
2. perform initialization sequence: meshtastic --set factory_reset 1 meshtastic --set gps_operation 2 meshtastic --set location_share 1 meshtastic --set position_broadcast_secs 30 meshtastic --seturl "http://www.meshtastic.org/..."
3. reset board and allow to sync GPS
4. from a second device, watch the packets (for example, using the Debug Panel in the app) - "position" messages should contain lat/lon/alt data
5. upload firmware-1.1.7.bin
6. perform initialization sequence (as above)
7. reset board and allow to sync GPS
8. from a second device, watch the packets again - "position" messages never contain lat/lon/alt data

Repeat steps 1-8 a couple times.

More info

• version 1.1.7 per commit 62a8c968e80c4e69755a7167232cddee023efe2e
• version 1.1.6 lost exact point, probably 4dd50df810780b6395701d3f10d31aea9247af8d

Additionally Could have been just a coincidence, but the GPS lock acquisition appeared to be slower with firmware 1.1.7. Not enough data to tell for sure.

Could not reproduce on further testing - possibly not a real issue.

Closing with apologies.
