PicoOta Ota over Uart

[em1rosales]

Hi friends, I am working with Pi Pico and need your help. How can I receive a .bin update file by UART? this file will be store in file system and then update with PicoOta, same to OTAFromFile.ino example. There are some library to manage the .bin file incomming by uart?

I doubt there is anything that exactly meets those needs, but look at the Arduino XMODEM libraries for a way of transferring binary blobs with some level of error detection over a UART port. Worked for 300 bps modems over analog phone lines. ☎️
