I am having an issue which I have seen reported multiple times but it’s not clear what (if any) resolution was found. When I do a BLE transmit string, my IOT device receives the data fine however my subsequent DO in the transmit process on Thunkable will not fire. Is the Thunkable BLE Transmit function expecting a response after transmitting? If so, what does that data look like? ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/d/7/d72b9ab6b074cd6391b9f12fdcc4bcd738089744.png) ---

If you set the value of a label’s text to the green error block, what does the label show? ---

I’m having the same exact problem, there is no return to execute the then do block. ---

Have you checked the `green error` block? ---

How do you check the green Error Block if it never gets to that then do. ---
