Hi Gordon,
at the moment I am trying to create a simple App Inventor application which should sends just a signal to Puck.JS or MDBT42Q to switch an digital output to high, while the button on the cellphone is pressen.
I´ve created a really simple test application with three buttons (1. Scan, 2. Disconnect, 3. Button for signal transmitting), furthermore a Listpicker to choose the BLE device.
I get the LED feedback from Puck.Js if I start the bt connection to Puck. So that seems to work but if I click on the third button to send something (e. g. a "1") I get no feedback. I am not sure, what I have to do on Espruino side. I started with the block diagramm at the Espruino IDE.
I used the following UUID´s on App Inventor:
UUID 6e400002-b5a3-f393-e0a9-e50e24dcca9e
UUID 6e400003-b5a3-f393-e0a9-e50e24dcca9e
Can you help?
Best regards
