Bluetooth LE Command 0x07 - Erase All Bonds
This command clears all pairing information about known Bluetooth LE hosts from the device. After
issuing this command, unpair the device from all paired Bluetooth LE hosts prior to trying to re-pair the
device. If any previously paired Bluetooth LE hosts are still in range of the device after issuing this
command, they may try to re-connect to the device, which would cause the device to stop advertising and
render it unable to re-pair. After clearing the device from all Bluetooth LE hosts, re-pair with the desired
Bluetooth LE host(s).
The command requires the host software to include a pair of Secure Code values in the request to make
sure the host software does not accidentally invoke this command.
After calling this command, either the host must send
power it off for at least 30 seconds, then power it on, before the changes will take effect. Because this
property affects Bluetooth LE communication, it is best to send it using the USB connection.
