PIC ROM reflash via Bluetooth
I think I duplicated this, but has anyone had success doing the above?
Probably not available, but I only need a simple to setup Bluetooth module with UART comms, no need for onboard extra I/O, A2D etc.
A 4871 refused to work, so I tried it with a cheap HC-06 module but the link is flaky and keeps dropping out. (Cost vs quality??) I know the re-flash code is ok because it works fine over a wire link using an FTDI-USB chip doing the same job.
The code sets/clears an EEPROM flag depending on re-flash success so even on failure, the chip will continue to work in limp mode even after a power cycle. However, the continual dropouts are frustrating so maybe it is not the best method, but hard wired updates are problematical.
