Hi Is it possible to change the MTU size with the Master Control Panel?
I am making a ble device on a nrf52 with the SDK 12 (latest softdevice) which has the ability to change the MTU size. On looking at the ble transactions using the nordic sniffer and the nrf dongle, the PC side says it is capable of 512bytes and I have set my nordic to say it is capable of 128 bytes (enough for my application). I thought that the two programs would pick the smallest one of these (128 bytes).
I cant see the BLE_GATTS_EVT_EXCHANGE_MTU_REQUEST being run on my device.
I want to test my device by writing more than 23 bytes to a characteristic using the Master control panel. (I can write less than that). Any more than that just does not send across the ble.
Any suggestions?
