CC2640R2F: the phone doesnt pop pairing dialog during pairing.

Part Number: CC2640R2F


I face an issue when I trying to pair with my android phone but it didnt pop passcode input dialog then pairing fail.

I am using BLE5 peripheral mode with these setting:

#if defined(GAP_BOND_MGR)
// Setup the GAP Bond Manager. For more information see the GAP Bond Manager
// section in the User's Guide:
// Don't send a pairing request after connecting; the peer device must
// initiate pairing
// Use authenticated pairing: require passcode.
uint8_t mitm = TRUE;
// This device only has display capabilities. Therefore, it will display the
// passcode during pairing. However, since the default passcode is being
// used, there is no need to display anything.
// Request bonding (storing long-term keys for re-encryption upon subsequent
// connections without repairing)
uint8_t bonding = TRUE;

GAPBondMgr_SetParameter(GAPBOND_PAIRING_MODE, sizeof(uint8_t), &pairMode);
GAPBondMgr_SetParameter(GAPBOND_MITM_PROTECTION, sizeof(uint8_t), &mitm);
GAPBondMgr_SetParameter(GAPBOND_IO_CAPABILITIES, sizeof(uint8_t), &ioCap);
GAPBondMgr_SetParameter(GAPBOND_BONDING_ENABLED, sizeof(uint8_t), &bonding);

These codes is working on simple peripherial example code, but I conuld not understand why it fail on my side.

Any idea to debug it??
