I have a problem with a couple of old GE863-GPS modules. After the expected April 7th 2019 GPS week rollover the GPS portion of the module stopped working. It might be due to old GPS firmware. Here's the info about the module:
As far as I could search this forum, I found that there is a newer version of the GPS firmware (GSW3.5.0Telit_3.5.00.00-C23P2.00a), but I can't find it anywhere. I have never flashed GPS firmware on Telit modules, but I believe it is done with SiRFFlash software and AT$GPSPRG command.
I would be very grateful if someone could point me in the right direction.
