Hi Prabhudurai,

Attached is the screenshots:

After that the LED3 on the nRF51 DK light up.

Please provide us a sniffer trace capturing packets when you are testing. Also please run in debug mode and check if there is any write event.

Prabhudurai: I don't know what else I can help you here. I don't have other advice beside what I suggested before. You need to understand what happens when the device doesn't want to bond and disconnect. Sniffer trace should be provided. Please provide the hex file that you used to test. Also please do nrfjprog --readcode filename.hex and provide me the filename.hex, after you have bonded with the iOS device.
