@wins&kooklaus: crc16_compute() should not cause an infinite loop. I guess you are seeing that because it's a long loop that take forever if you just stepping by pressing F11. You can try to add a breakpoint after the call.

What exactly happens when you program the stock example in the SDK v7.2 ? Do you see the device advertise as "DFUTarg" ?

@kooklaus: Please create another question with more information on your setup and how the issue occurred.

@wins: Which chip version do you have ? The new S110 v8.0 by default uses features that are not available on the older chip. Please have a look at the release note of the S110.

@hungbui can you provide adresses and limitations??? for DFU with nrf51. Coz if I use hex files from devzone.nordicsemi.com/.../ and upload it with nrfjprog - the device start to adv. DFU option.

I have exactly same issue. I have nRF51822 QFAAG2 (IC revision 2) and using SDK8 running on S110 v8.0.0. When the program executes crc ^= p_data[i]; in for loop of crc16_compute(), it goes off.

@wins: It's fine to have dfu_ble_get_peer_data() return NRF_ERROR_INVALID_DATA. This means you have no bonding information passed from application. If you start DFU bootloader straight from power up you should have this NRF_ERROR_INVALID_DATA returned. I suspect there must be smth else went wrong. Have you tried the DFU example without any modification ?

To be able to properly debug DFU you would need to change the Optimization level to 0 . Please follow this link on how to debug with the bootloader.

Note that you would need chip version at least 2 to be able to run S110 v7.1.0. Please take a look at this matrix table to know which version your chip is.

@wins: Please add information on which SDK you used
