you need to read it from server, so sd_ble_gatts_value_get

Thank you for your answer. I will try to implement this. I imagine I have to use sd_ble_gattc_value_get in order to read the data?

Sorry for the late reply Tom, I was thinking that I replied to this thread before leaving to vacation, not sure what happened but it was not intentional.

[quote user=""]I know how to set up the characteristic and using NRFConnect I am able to read from the characteristic but I do not know how to update the data on the peripheral side. I was able to use the p_init_value pointer to set the data but I am not able to update it afterwards.[/quote]

Have you tried using sd_ble_gatts_value_set. This should be enough to set the value of the characteristic up to date when you have new data. I am not sure why you do not want to have notifications enabled for this, but the above function seems enough in your case.
