[Bug]: Meshtastic: No GPS

Firmware Version
2.3.13.83f5ba0
Description
After upgrading Meshtastic to 2.3.13, the CanaryOne device stopped detecting the GPS module. All settings seem to be OK. No setting changes or multiple reboots or factory reset restore position recognition. "No GPS" and "No GPS present" are shown onscreen.
It should be noted, that after unboxing the CanaryOne presented the position in the right way.

Thanks for reporting. Is it possible for you to attach serial logs?

I just installed the GPS module and it doesn't work. It appears to me what the user above mentioned. I checked the connections several times. It runs version 2.3.15.

I followed the steps from here: https://meshtastic.org/docs/hardware/devices/heltec/peripherals/
P.S. I found out why the gps modules were not working. The transistors were to blame, even though they were new, they didn't work. I removed them and everything is ok. Version 2.4.0.46d7b82 Alpha is currently installed.
The log from Flasher is here:

As it is coded (encrypted?) I don't know if there are interesting informations. Anyway, I have some logs from Python CLI and I am ready to send them for further investigations.
Switching the ground of the GPS module with an NPN transistor is NOT good engineering practice.IMHO the Meshtastic docs page should be changed to reflect this. While it may "work" in some cases there are many reasons why power control of the GPS module should not be done this way.
Hi @ms74ro @LoRa-user - there have been some updates to the GPS detection code that went in to the 2.5.0 alpha. Are you able to give it a try?
Fixed by https://github.com/meshtastic/firmware/pull/5014 - Try 2.5.7 when released.
