Hi team,
I am developing a BLE central and peripheral applications with using CC2642R. Without pairing and bonding everything works perfectly. Central can discover and connect each other.
However, I am facing a problem while enabling bonding.
When I enable pairing and bonding, both devices goes through GAPBOND_PAIRING_STATE_STARTED => GAPBOND_PAIRING_STATE_COMPLETE => GAPBOND_PAIRING_STATE_BOND_SAVED.
After bond_saved I checked the bondCount in both devices and both result is 1.
However, while I terminate connection after bonding. Devices can not communicate again if I am not erasing bondings.
After termination of connection, central can discover the peripheral and attemp connection. I got GAP_LINK_ESTABLISHED_EVENT from each devices. But, I couldn't get any event from GAPBond_Mgr
However, I can't send data from central to peripheral or vice-versa.
After a while, the link is terminated with reason 0x22.
What could be the problem, I couldn't figure out the situation after reconnection without erasing the bonds.
