I have an Arduino Micro and ESP-01 module talking to each other via I2C and Serial TX/RX. So far, so good…
Until now I use two seperate USB cables for uploading:
- Arduino Micro: directly
- ESP-02: via ‘CP2104 USB to UART Bridge Controller’
Is it possible to upload/update to both devices using only one Aruino Micro USB port?
When I sell this product, it has to be possible for the client to do a software update via USB.
The Arduino is directly reachable, but the ESP is connected via I2C and Serial TX/RX.
Or the other way: upload via Over-the-Air to ESP-01 and Arduino Micro?
