Hello Sir,
I am currently working with the nRF52832 (for testing purpose, later will use nRF52833 for final product) as a central device using the nRF Connect SDK. In my implementation, the central device scans for peripherals and establishes a connection upon detecting a specific custom UUID in the advertising packet.
After the connection is established, the central performs service discovery. Once the discovery is complete, send a write request to the connected peripheral to initiate data transmission. The write command executes successfully, and I have also implemented a callback function to handle incoming data from the peripheral.
However, although the callback function is triggered as expected, the data received is null. I have reviewed the relevant documentation regarding write requests, subscription, and callback handling, but I may be missing a key step in the process. Could you please advise on what might be causing this issue or suggest any additional steps required to ensure proper data retrieval from the peripheral?
