CarPlay solution for Tesla by Michal Gapinski using Raspberry Pi with Android

So just finish installing 44.2 and still the Alcatel USB LTE Modem does not connect the cellular network. Keep having the blue flashing light which means - found LTE network and trying to connect. If all works the light turns solid blue (means it connected) - which I get when I connect the Alcatel USB LTE Modem through my micro router (so both the modem and my cellular plan is working when connected to another computer). I think the problem could be with the string Tesla Android is using to enable the cellular network which works with some but not other cellular networks. I am using T-Mobile.
What cellular network are you using?
I have the same Alcatel USB LTE Modem and am also on T-Mobile. Mine has no problem connecting. I think the author suggested to someone facing similar issues to make sure the power supply is providing enough power to the pi. Aside from that, not sure.
Thank you. Will check. Although I am using the T-Mobile network, my provider is actually Tello. No other computer sees the difference between T-Mobile and Tello and actually all are set to use T-Mobile and it works. So, if it is not the power supply it could be some nuance with Tello and Android Project???

Doesn’t work. I reported issue on GitHub & will supply Michael with some debugging info he requested. I’ll do this in a few hours during my afternoon mandated 15 minute break

Interesting pattern. My provider is tello too which uses t-mobile network & my Alcatel is not working on tesla android but works on windows. Michael asked me for some debugging info which I’ll get to him today.
My pi is powered via cigarette lighter usb-c adapter which supports 100Watts power output. Lte stick powers on according to status lights.
So it seems a particular issue with how Tesla Android is enabling the cellular network that is not working with Tello??? Since we are both experiencing the exact same issue with Tello and others with different networks including T-Mobile (minnesnowta) are working.
My modem, from the eBay order is an "Alcatel LinkKey - IK41UC | LTE AT&T / T-MOBILE UNLOCKED USB Internet Dongle". Works fine for me, my carrier is AT&T.
Yes, same modem as mine and ElectricAnt54 but with a different cellular network - in your case AT&T - in our case Tello. It is looking like an issue of how Tesla Android is enabling the cellular network that is not working with Tello. My same modem and Tello network combination works fine on my Windows and a micro-router I have so I know it works, just not with Tesla Android.
Checked the power supply - it is specifically for Pi4 and provides 3.5 amps. I checked with a dongle I have and it is steadily working and providing full power. So since ElectricAnt54 is experiencing the same issue with the Tello network, I think the problem is how Tesla Android is enabling the cellular network that is not working with Tello.
Yes, agree. I have a similar tester with a load adapter and that is what I used to check the power supply capacity for 3 amps and it passed.
I got this tester that comes with the load adapter:
Also got this additional tester to test PD and QC voltage power supply capabilities:
If you get this voltage tester be very careful and do not connect your phone or any other device to it since this voltage tester forces the voltage no matter what the device accepts. It is to test the power supply only and by itself. If you connect a device to it and force a voltage that your device does not accept it will fry your device.
Make sure "Internet" is enabled for your paired phone in the Pi's Bluetooth settings.
I think a script is needed to automatically enable that toggle.
