I hate that it needs to be said but love that they said it so plainly

Installed it in k3s and then pulled up the Android app but all it does is say every single file is a duplicate and overload my notifications tray while not uploading anything

Yeah, that’s the issue ultimately. The ESP32 chips are nice and easy to use but still pale in comparison to getting things working on a pi for the average developer without embedded experience. These devs may not even know they exist to be completely honest.

I’m not intimately familiar with the BCM2711 but I believe it’s a reasonable, albeit somewhat overpowered, processor for the application. It can be put into a variety of low power states and probably pulled out of sleep by various events like the GSM chip sending packets or accelerometer motion (frequently the peripheral chips have dedicated “wakeup” pins that you can wire to interrupts). It’s not the most cost effective option by far, there are sub $5 microcontrollers with multiple cores for handling communications and real time motor control concurrently but you’d need to hire someone like me for a few months @$200/hr to write the low level drivers and design the boards. The rpi lets random web-only devs fumble their way through hardware development using whatever GitHub Python libraries they can find. If you only need a hundred scooters it makes more sense to just yolo it and buy up the remaining supply of rpis to start your grift.
