Arduino Uno Wifi and HC-05


I just ordered a Hc05 BT module for my Uno Wifi.

I have read that the Hc05 needs to be disconnected before you can transfer your sketch via usb, is this also the case when i use ota via the onboard esp8266 which uses I2C?



Hi again.

I have now testen this on my Arduino Uno Wifi, and it works :slight_smile:

The HC-05 module connected to tx and rx do not interfere with the I2C onboard esp8266, I am still able to transfer a sketch OTA with the Hc05 connected.
