Wio with UART grove module doesnt start when usb plugged in

Post by email4kai » Sat Jan 12, 2019 11:44 pm

Hi,

I have a wio tracker with grove uart bluetooth module (HM11) attached.

The tracker script doesnt start, if I plug the usb power cord. I must do a reset, bevor the script starts. I'ts only when uart module is attached.

I have made a test script, with only led use. It has no effect, if I use the SerialUSB/DBG Communication or not.

Any hints or suggestions ?

Kind regards

Kai
