Hi folks,
is somebody running bluetooth via HC-05/HC-06 and is able to connect with speeduino via USB?
I do have an HC-06 connected to RX0/TX0. Communication works fine
Then I stop the HC-06 communication in Tunerstudio, plug-in USB and try to connect via USB --> doesn't work
Disconnecting the HC--06 from power and USB works.
The HC-05/06 is pulling the Arduinos RX0 HIGH, as soon as the HC-05/06 is powered up. This is independent if I run it through the level shifter or RX being directly connected. I think this isn't specific to Speeduino but rather a generic Arduino issue. It happens on both my original italian Arduino Mega board as well as the DIY-EFI CORE4 module.
I would want to have both connected in the car: Bluetooth for regular TunerStudio work and using USB for Firmware updates. Removing the ECU from the car is a major PITA hence having both cabled at the same time and connect to the Laptop via one or the the would be a benefit.
I hope somebody has aclever idea here. Thank you!
