@sandipg No, sadly the ESP32 microcontroller we use will not support Bluetooth 5.

@jmarcelino Hi Sir, I have not forgotten you and others. If you recall, I had Pucks, and WiPy modules with RFduino's. I did get into Simblee's of which uses Arduino to program. Very low power, small, lots of IO's etc. Have success with the parts and made lots of prototypes. They are MSL 6's, so they need to be baked if not properly shipped. The issue now is the Simblee had received RED qualifications and all vendors ran out of parts. So I'm stuck. Ugh. I looked back into WiPy, but it still Py programming. I just wanted to say hi and thank you for pointing me to look at other items. Wayne
