Cannot Re-pair nRF8001 in iOS

The Arduino sdk will store bond data in the EEPROM and restore (bond_data_restore) it when the nRF8001 restarts. Bond data is normally deleted by connecting pin 6 to 3.3v. You can see this on the serial print if you use one of our examples.

Just to confirm, I tried a hard power cycle on the nRF8001: Paired with iPhone, told iPhone to forget nRF8001, power cycled the nRF8001, tried to re-pair. Same results; connects but iPhone doesn't receive key presses.

Thank you for the reply. The problem persists even after toggling the reset pin on the nRF8001, which I assume would wipe the bonding data on it. If that doesn't wipe the bonding data, would you mind telling me how to do so? I'm using the Arduino SDK and see no way to clear the bond data from the nRF8001, only upload existing bond data to it. And yes, I have debugging turned on, so I should see all events, and none of them have been errors while reproducing this issue.

If you delete the bond in iOS you will also have to do this on the peer (nRF8001), did up do this? Since iOS is changing it's address every 15 minutes, we cannot enable the white list when bonded to an iOS device, which is why you are able to connect to the device again.

Are you checking for pipe error events? You should also make sure that you are saving and restoring dynamic data correctly on the nRF8001 so you don't lose the bond information on power toggles.
