change ble_app_gls without passkey

[bou]

Hello

I need to do pairing with Android devices without passkey in ble_app_uart example.（ Device nRF52832 ,SDKv16.00, softdevice S132 )

I use ble_app_gls  example and Android Toolbox app ,Changed to #define SEC_PARAM_MITM 1 to #define SEC_PARAM_MITM 0.

However, the tablet displays the device has refuse the pairing.

Are there any other changes I need to make?

Best regards,

Hello,

The pairing request shouldn't be rejected because you have disabled the MITM bit. Could it be that the pairing request is trying to update an existing bond in your case? The default behavior is to reject any  attempts to update existing bonds as I mentioned in this post: https://devzone.nordicsemi.com/f/nordic-q-a/51965/pairing-and-bonding-after-deleting-synchronization

Hi, Vidar Berg

Thank you for your reply.

I  erased only bonds on the android side.

I also erase bonds on the device (nRF52832 ) and can be paired.

Is there a way to automatically erase the bond on the device side when the information is deleted on the android side?

You can set the "allow repairing" flag. It doesn't delete the bond information but it allows the central to overwrite the existing bonding information. So it should have the same effect.
