RE: nrf52832: sending BLE values

Hello,

[quote user=""]Maximum MTU size is 251.[/quote]

Are you referring to the Bluetooth SIG specifications?
The maximum data length available to applications is in fact 244.
The remaining 7 bytes are used by the SoftDevice.
You can look this up by the defined NRF_SDH_BLE_GATT_MAX_MTU_SIZE(which is 247, minus OPCODE_LENGTH and HANDLE_LENGTH).

Could you constrict your application data to 244 bytes per package, and see if it then performs as expected?

Best regards,
Karl
