Hi,

I do not immediately see any problems. How did you solve the isse, and what does the code look like now? Also, what do you ant to acomplish?

Note that there is also an SDK module that handles queued writes, which may be relevant.

Hi ,

Thank you for your answer.

yes, I did not show the BLE_GATT_OP_WRITE_CMD command.

I have solved this problem.

Could you please help me to confirm whether it is correct to use prepare write request like this.

thanks, I wish you a happy life and work well.

Hi,

I do not see the code where you send the BLE_GATT_OP_WRITE_CMD command (and get NRF_ERROR_INVALID_PARAM returned) in the code snippet above. Can you point to the exact code snippet where you get this error?
