bluetooth lowenergy - How to change BLE pin programmatically

Question

Can we change passkey (4 digit pin) in Bluetooth Low Energy? How to change it programmatically ? FYI : I using sensortag cc2650 and https://github.com/don/cordova-plugin-ble-central

Answer 1

No, it's generated by the internal bluetooth stack. By the way it is 6 digits, not 4. You shouldn't change it anyway since it should be a randomly generated code. The standard says:

If the IO capabilities of a device are DisplayOnly or if Table 2.8 defines that the device displays the passkey, then that device shall display a randomly generated passkey value between 000,000 and 999,999.

If you don't need a code you should use the "Just Works" pairing method.

Why would you like to change the code?
