Hi james,

Could you provide some more information:

• Which SDK and S110 version you are using ?

• Do you have any problem with updating the application instead of the bootloader ?

• Do you have any modification to the bootloader ? If you try to simply update the bootloader with same image do you have any issue ?

• You can find more information on what was wrong by looking at the log, you can find the log by using nRF Connect and swipe right to see the log.

• If you have nRF51 dongle or DK, you can use the sniffer to capture a trace. It would be very useful to see the trace.

Hi Hung, 1.I use SDK v9.0.0.

 2.I use application of ZIP to update, it works fine.

 3.I had modified the bootloader,I changed the dual_bank_ble into single_bank_bank.

 4.I don't how to use nRF Connect while ble connect the nRF Toolbox.

Hung, I had tried to use the primary bootloader procedure, but it still stop at 1%.

Hi James,

What do you mean by "primary bootloader procedure" ?

nRF Connect has its own DFU you don't need to use in parallel with nRF Toolbox.

If you only test with dual_bank_ble do you have the same problem ?
If you do no other modification except for changing from dualbank to single bank, would you have the issue ? If you do , please attach your bootloader so we can test here.

I apologize for my expression. I mean I use the original bootloader.I use nRF connect to test the update,I find it can update by zip file, but it can't update by hex file.
