  • Topic: Connecting two Blunos
    You Reply: I did everything you suggested and managed to upload the script. Thank you very much!

    The mistake was the power supply. I had to power the MEGA board through a usb port without serial connection, so not through a PC.

    However, I noticed that it is possible to upload a sketch to the nano board, only if the MEGA is not powered (no connection).

    In the interative project I build, the Nano will be placed in a moving part, thus it will be super inconvenient to programm everything through the Nano. I was wondering if it is possible to have it the other way around. To program the nano through the MEGA.

    You Reply: I did the AT Commands as described and binded the MEGA MAC address in the nano bluno. I got an 'OK' as feedback in all the AT commands I inserted. The link LED in both blunos is on, but now I cannot upload nothing in both bluno nano and MEGA. The serial ports are proper selected.

    Nano error:

    You Reply: I used UNO as a burner and followed the link. However the error led blinked two times in the beginning for a short time while running the burn bootloader. And if I try to upload a sketch to the Bluno ATMega 2560 the same error occurs.
