changes for old v1.0 TTGO-T-Beam

chgerwig commented 2 years ago

I cloned the repository to find out what have to be changed in order to be able to use this code for TTGO-T-Beam v1.0 I found already the GPS pins, but what give me headaches is how to remove the AXP deep sleep. Can you please give me some hints where it is sitting and what have to be removed. I am also wondering how to disable geofencing. btw. I always get a warning of the compiled that the variable geofencing is not used. But I have not changed the location.h file.

The AXP-Part is only needed, because you have to manually enable power for the GPS. Later on it is only used to get the battery status. If this chip isn't on v1.0 you can remove that part(power.*) entirely because it is only for the AXP-Chip
You shouldnt be worried about that warning. It pops up but this variable is used later on in gps_geo(). If you dont want to use geofence just dont use gps_geo() in sendLocation()

Oh OK now I can see the problem. The project doesn't compile anymore :/

Right now I'm busy with other things but next week I will look into it

I'm sorry I've got a lot to work right now but if you would specify more of your issues I can give you some advice

Since I don't have a TTGO-T-Beam v1.0 I can only guess :/

T-Beam v1.0

It seems that it also has the AXP192 Chip for power management so you have to include that like in my original program(I'm sorry I haven't looked at the board before I just knew the older ones dont have this power management chip so I just guessed based on your first comment). You have to speak to this chip in order to tell him to power up the GPS. Ohterwise It won't work

Also only the pinout of SDA and SCL seems to have changed(probably to make it easyer to solder on a display)

Have you tried to run my original Programm with just the credentials changed? because I cant see the reason for not working from my first glance

Also worth a note from personal experience: The the NEO-6M GPS with its little antenna takes ages to get a fix, expeccialy if it was never used before. So just let it sit outside for a day or more. I also thought the GPS on one of my boards was dead but suprisingly it started working
