As mentioned here, the function sd_ble_gatts_value_set() can update the local database on the server side as well as notifying it to the client. Read more here for a more detailed explanation of the function.

How do you confirm that the database on the server side is not updated? Try to read ble_gatts_hvx_params_t::p_len after calling sd_ble_gatts_value_set(), if it is a non-zero value, then you know the database has been updated.

Best regards,

Simon

What is sd_ble_gatts_value_set() actually do? It seems not really update to the database of server side. Or I should only do blcm_link_ctx_get() to write database?

Could you be more specific? What is your problem exactly? The question regarding sd_ble_gatts_value_set() or the question regarding link context manager? The developer in the provided link also posted an answer. What specifically about this did you not understand?

Best regards,

Simon
