Device Firmware Update over BLE

[Lora]

Hello,

I work on project for BLE communication in DFU mode.

I am testing according to the mode defined on the Nordic web page link

I did the tests with the BleuZ and with an android application nRF.

I start with enable CCCD, then I write the [01 01] on the characteristic DFU CONTROL POINT and [14 0 0 0 0 0 0 0 0] as size of the packet on the other hand on the response I always receive [10 01 03] knowing that I must receive [0x10 0x01 0x01] -> decimal [16 1 1].

 

could you help me please.

Best regards,

May I ask why you are using sdk 11 with the nrf52 dev kit? If I may suggest, I would recommend taking a look at this great blog post written by an application engineer here at Nordic. It explains the DFU process step by step. In addition, you can use the BLE Secure DFU Bootloader example in our latest sdk 15.
