TinyDuino Processors & TinyShields / Re: USB TinyShield and Bluetooth

I've found what seems to be a solution. Full disclosure: I know next to nothing about C++ or Arduino programming.

The BLEsetup() function in the setup loop would never terminate. I added a return control at the end of that function (which lives in the UART.ino) -- that fixed the issue. Maybe that's not the best way to do it, but for now I am able to pass data back and forth via the BLE connection.

I'm all ears if there is a more correct solution.

I'm also having trouble getting the UARTPassThrough sketch -- the example in the STBLE library -- to work. I'm using the Arduino IDE (1.8.8) with a TinyDuino Basic Kit (Coin Cell), BLE TinyShield (ST) and accelerometer TinyShield.

In my case, it appears the sketch never escapes the setup() block. At 9600 baud the serial monitor spits O(10) garbage characters (e.g. BLE StacQ⸮) and then nothing else. At 115200 baud the serial monitor floods with repeated BLE Stack Initialized ... UART service added successfully. messages. In both instances the baud rate set in the sketch and in the serial monitor window match properly. Screenshots attached.

In neither case does the chip become discoverable to scanning devices. I'm new to this whole Arduino/TinyDuino scene, so guidance from you more experienced folks is very welcome! (I emailed info@tinycircuits late this afternoon, but I figured it wouldn't hurt to ask here too.)
