nRF52 data length extension

[Rajneesh]

Hello Nordic team

I am working on nRF52832 DK and SDKv-11. Can we increase MTU size to send more than 20 bytes in one packet? If yes then any example code do that?

Is our nRFConnect mobile application can receive more than 20 bytes data in characteristic?

Regards,

Rajneesh

Hi,

I suggest to download the latest nRF5 SDKv15.2, then you can run the ATT_MTU Throughput Example on how to increase MTU and data length, and measure the throughput with the specific parameters: https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/ble_sdk_app_att_mtu.html?cp=4_0_0_4_1_1_0

Thanks Kenneth

Does nRFConnect android application support to Data Length Extension?

[Kenneth]

I believe so, but of course that will depend on what the phone support also.

I have BLE-5 supported phone. Hope nRFConnect can receive more than 20 bytes.

Could you please send me the link of DLE supported nRFConnect mobile app source code?
