This is the Github repository for the BLE_API
. Please see the Mbed OS Example BLE GitHub Repo for all code examples, and the Mbed OS BLE API page for all code documentation and general help.
The Cordio Bluetooth stack only stores one single signing key. This key is then shared across all bonded devices. If a malicious device bonds with the Mbed OS application it then gains knowledge of the shared signing key of the Mbed OS device. The malicious device can then track the Mbed OS device whenever a signing write is issued from it.
To overcome this privacy issue do not issue signed writes from the Mbed OS device. A signed write occurs when the member function write
of GattClient
is called with its cmd
argument set to GATT_OP_SIGNED_WRITE_CMD
.
Instead of using signed writes, enable encryption on the connection. This is achieved by calling the function setLinkEncryption
of the SecurityManager
. Set the encryption to at least ENCRYPTED
.
