Device Bonding

This library does not provide possibility to explicitly create a bond with a peripheral.

There is a possibility that a bond will be automatically created by the OS. This usually happens when a read/write request is sent to a characteristic that needs encryption.

The usual process on a low level looks like this:

1. Central sends a read/write characteristic request to a peripheral
2. Peripheral responds with GATT_INSUF_AUTHENTICATION/GATT_INSUF_AUTHORIZATION
3. Central—OS intercepts the response and kicks off bonding procedure

After the bond is created the iOS automatically retries the request that was responded with the GATT_INSUF_AUTH* whereas Android returns an error and a manual retry should be performed.

Notes:

• On some Android versions there is a bug where the bonding is randomly lost
