Bluetooth Low Energy Receive not working

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


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