T-TWR Rev 2.1

[technash85]

Hello,

I have a Rev 2.1 T-TWR from Lilygo. I've flashed the firmware for the Plus and most everything seems to be working except for the GPS. Should I try the firmware for the 1 instead? Any other ideas?

Thanks,

V1 is not supported without HW mods and have totally different OLED and GPIO, as well as other hardware realted stuff. DON'T USE IT! This target was only for testing purposes.

V2.0 is what I have on a table and around 10 devices are online, all working ok. Looking to V2.1 schematics (I don't have this version) https://github.com/Xinyuan-LilyGO/T-TWR/blob/master/schematic/T-TWR-Plus_Rev2.1.pdf and comparing with V2.0 https://github.com/Xinyuan-LilyGO/T-TWR/blob/master/schematic/T-TWR-Plus_Rev2.0.pdf I don't see any differences in GNSS part, nor module, nor powering, nor GPIO. It should work.

Maybe you are not outside? L76K GNSS used in T-TWR together with 1/3 size of normal patch antena need clear skyview and some time to obtain fix. Or, maybe, your HW is just broken.

Thanks much! Just needed to go outside.
