        I now use nrf52832 to do development, nrf52832 and mobile phones to transfer the data is relatively large, I would like to achieve For mobile phones that support BLE4.2, a single air package can send 250byte, for the unsupported phone to send 20 Bytes per package, whether There are such routines or tutorials, thank you!

Hi,

You can use the SDK GATT module to request MTU and data length updates from the phone. It will still work with phones that do not support long MTU and DLE.
