Topic: Big disappointment...
Hello,
Your system is great, but you're too ambitious. You want to do too many things, and in the end, almost nothing works properly...
For several days, I tried to get a basic program working on a DFRobot Beetle BLE module. It's impossible to find a combination to access this module with Bluetooth mode in your device configurator. Your selection system seems absurd to me...
Sorry, but I'm going to look for a solution elsewhere...
