nRF51 S110 v8 buttonless DFU-OTA

[Renga]

Hi, I am facing issue on nRF51 s110 buttonless DFU. We are initiating DFU using nRF Connect and the device jumps from app to bootloader. On my Android Phone using nRF Connect I can see the DfuTarg. But nRF Connect stays at connecting state and eventually timed out. Bonding info is shared and on device app MAC address type was set as BLE_GAP_ADDR_TYPE_RANDOM_STATIC.

SDK version 8.

Regards, Renga.

I think newest version of nRF Connect is not compatible with old bootloader available in SDK 8. You may try to:

• Find some older version of nRF Master Control Panel (previous name of nRF Connect) and try with them - some version should work, but cannot tell you which one.
• Modify bootloader so it is compatible with the new one available in newest SDK
• Write your own app for DFU (instead of nRF Connect)

nRFConnect should be compatible with all bootloader versions. I would assume if you open nRFConnect again and do DFU after the device advertise as DFUTarg it would work ?

Have you modified anything in the bootloader and the buttonless DFU example ?

Could you capture a sniffer trace ?
