Hello folks, I am trying to receive data from ESP32 with Nordic UART characteristics on the app as shown in the Blocks. I have successfully transmit the data. In receiving i have used 100 ms timer in loop to continuously read data but i am not able to read the characteristic. please verify and suggest anything is missing Thanks ![Capture](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/1/5/153e135b8149089c81cf165afb1c2116441a7d13.png) ---

in both the transmit and receive blocks, can you display the contents of the error blocks in labels? what are the values? ---
