CC2340R5: How to erase a specific bond (by MAC address) instead of all bonds?

Vaibhav Patil

Part Number: CC2340R5


Tool/software:

Hi Forum,

I understand that we can erase all bonding information using the following API: GAPBondMgr_SetParameter(GAPBOND_ERASE_ALLBONDS, NULL, NULL)

However, my requirement is to delete only one specific bond, given the device’s MAC address (BD_ADDR). Is there a way to do this using the GAP Bond Manager, or any workaround?

I don’t want to remove all bonds—just the one associated with a particular MAC.
Is there any API like GAPBondMgr_RemoveBond() or another recommended method to achieve this?

Thanks in advance!

Regards,
Vaibhav

    Hello Vaibhav,

    Thank you for reaching out! I believe what you're looking for is the GAPBOND_ERASE_SINGLEBOND. It should be the parameter used inside GAPBondMgr_SetParameter().

    I hope this answers your question!

    Hi Tarek,

    Thanks for reply, i was looking to erase a particular bond using MAC. May i know if i use "GAPBOND_ERASE_SINGLEBOND" flag, which bond will erase in bond table? i mean to ask, say i have 3 device in my bond list, so which one will erase if i use above flag?

    And is there any work around for reading all bond entries and deleting particular bond info manually?

    Regards

    Hello Vaibhav,

    To delete the particular bond, you would need to use the GAPBondMgr_SetParameter() API, and pass into it the macro GAPBOND_ERASE_SINGLEBOND, followed by the size (7 Bytes), followed by the pointer which points to address type followed by a 6 byte address, which will be the MAC address. Please use the links I provided earlier as reference.

    I hope this answers your question! Please let me know if you still need help with implementing this.

    Best Regards,
