Hello,
I need a quick solution for a project (a small robot) but I should be able to reprogramm it over the air.
As I'm a big fan of Teensy boards, I'll use one of them (Teensy 3.2) but, as far as I've read, there's no OTA sketch uploading available (due to locked bootstrap or something).
ls there any other alternative? Like installing a NodeMCU + Lua or a RTOS?
As I don't really need to reset the device everytime I need to reprogram it, I thought of just "refreshing" a small part of it (an algorithm/procedure) to tweak some sensor inputs and to adjust some actions (driving the motors).
As an emergency solution, I am thinking of some sort of client/server operation, where the Teensy board will have a "read-only" firmware (for simple commands like reading the sensors and driving the motors) then I'll use a Raspberry Pi to do the math and to control the Teensy actions (through a python script or something).
I could have used the RPi alone for that matter but I need a low power MCU on that robot. Btw, I have some ESP8266 and RF24 boards available for the wireless support.
Any help is greatly appreciated, as it supposed to be a Christmas gift for my son (and an introduction to embedded world).
