5.12 Change Simple Pairing Parameters

Description

The ChangeSimplePairingParameters command is responsible for changing the Secure Simple Pairing Parameters that are exchanged during the Pairing procedure when Secure SimplePairing (Security Level 4) is used. This function returns zero on a successful execution and a negative value on all errors. A Bluetooth Stack ID must exist before attempting to call this function. The IOCapability and MITMProtection values are stored in static global variables which are used for Secure Simple Pairing.

Parameters

This command requires two parameters which are the I/O Capability and the MITM Requirement. The first parameter must be specified as 0 (for Display Only), 1 (for Display Yes/No), 2(for Keyboard Only), or 3 (for No Input/Output). The second parameter must be specified as 0 (for No MITM) or 1 (for MITM required).

Command Call Examples

  • "ChangeSimplePairingParameters 3 0" Attempts to set the I/O Capability to No Input/Output and turns off MITM Protection.
  • "ChangeSimplePairingParameters 2 1" Attempts to set the I/O Capability to Keyboard Only and activates MITM Protection.
  • "ChangeSimplePairingParameters 1 1" Attempts to set the I/O Capability to Display Yes/No and activates MITM Protection.

Possible Return Values

  • (0) Successfully Pairing Parameters Change
  • (-6) INVALID_PARAMETERS_ERROR
  • (-8) INVALID_STACK_ID_ERROR
