Say I have a bootloaded Arduino chip with Bluetooth channel on the TX/RX pins. I would like to flash it via the bluetooth serial port, without an IDE .
That means I would like to compile on a pc/mac , get the hex file, and then send it over BLE from another environment like iPhone for instance .
Is it just about sending the hex file as a regular string over serial and turning the reset on time ?
Is there any replacement for the avrdude so its portable ? what one would need to write such a program that uploads the hex and flash it from any environment ?
Thanks a lot.
