Hi team, I am using an HM-10 module, communicating via UART\serial pins on an Arduino board, to communicate with the BLE object in an iOS application. I can use the “Transmit String” successfully, in fact was amazed at how easy this function was to establish. Unfortunately I’m unable to “Receive String”. I have a label used to trap error messages from the BLE object and it reports no error, and another label to display the returned string from the HM10 and it returns no data. My thunkable code blocks are below: ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/4/1/41eabb5ff4d658412bccfabb7d46d9e5e27f4198.png) ---
