NRF 52 DK ble dfu VS Android NRF Connect DFU speed diifference

Hello Nordic Devzone fellowes

I tried DFU with NRF 52 DK board with 'PC-BLE-DRIVER-JS' dfu.js test code

When the firmware .zip file is 128 KB the speed of transftering the file is 600 Bytes / sec

However When I try with NRF connect App on my Android phone (Sony Xperia XZ premium)

it has 1.6 KB / sec Which is way faster than when I tried with NTF52 DK board.

If anyone know why there are difference please let me know

and is this something I can improve by modifying Source code of 'pc-ble-driver-js'??

Thank You.

  • Hi, 

    I'm sorry indeed for the late response. I was on vacation. Do you still have problem getting the sniffer working ? We do have issue with the sniffer on some computers. You may want to try sniffer v1.0. 

    If you don't have the sniffer, you still can find the connection interval by looking for the connection parameter when you receive the BLE_GAP_EVT_CONNECTED event (either on the central or the peripheral). 

     

    We will try to have a look at the dfu.js and get back to you as soon as possible.
