I'm using Nrf connect for Mobile to test my BLE firmware. I noticed that when trying to write more than 20 bytes to a characteristic, nothing gets logged which means my write callback function isn't called. Either the nrf connect app isn't sending anything above 20 bytes or the BLE stack is just silently ignoring the message for some reason. According to BLE spec, characteristic value can be up to 512 bytes so that's a bit unexpected. Am I doing something wrong? I attached my prj.conf and some code.
