No GPS on TBEAM0.7

[notthetup]

Describe the bug
I flashed the latest beta (also tried alpha) release on a Tbeam0.7 and I see No GPS on the screen even after the GPS PPS LED starts blinking..

Device info:

• Device model: TBEAMv0.7
• Software Version : firmware-tbeam0.7-1.2.52.b63802c.bin

This is the command I used for flashing..

./device-install.sh firmware-tbeam0.7-1.2.52.b63802c.bin

Flashing log seemed fine.

Trying to flash firmware-tbeam0.7-1.2.52.b63802c.bin, but first erasing and writing system information

Yikes! I realised that I have TBEAM v1.x instead of a v0.7.

I went through the list of TBEAMs here https://meshtastic.org/docs/hardware/supported/tbeam to find the one which looks like mine, and got confused.

Sorry!

[caveman99]

the 3 pushbuttons are a dead giveaway for a 'tbeam'. The 'tbeam 0.7' has a mechanical switch near the USB port.
