I am having issue with a BLE Transmit string method. Using esp32-wroom and BLE UART standard example from arduino-esp32 library. Project was testing with thunkable android app.
I can connect to the esp32, no problem. When I call BLE transit string on button click it transmits string to esp32, but never execute Do section. The same problem is described here - BLE Transmit never triggers DO
Here is my transmit string block. Set label’s text to Error doesn’t works - even Vibrate not executed. The connection part of the App executes Vibrate well.
And modified version
Label with a debug output (label_ble_status_info) newer shows “Done” and there are no phone vibration at all.
