I think that the issue with this project is related to send and receive int32 data to/from Thunderboard using AppInventor.
I set "shorts" instead "integers" and I managed to receive some data, but only halp, because shorts is int16.
For lightup the leds from Thunderboard, I have to send this info:"1FFFFFFF"; this is an 4 bytes (32 bits) and seem that the AppInventor don not sent this...
Do you have any other information regarding to how should I send/receive int32 with AppInventor?
Another thing: if I set Register for Integers, then the application stop to display new arrived data over BLE.
Thank you,
Mihai
