CCS/CC2640R2F: Pairing problem! Device can't be paired. custom board with revised simple_peripheral program.

Hi Shuang,

Can you post your pairing/bonding settings? Also, can you post a sniffer log of this happening?

uint8_t pairMode = GAPBOND_PAIRING_MODE_WAIT_FOR_REQ;
// 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.
uint8_t ioCap = GAPBOND_IO_CAP_DISPLAY_ONLY;
// 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);


Here is the pairing setting. Although there's no display to show the passcode on my board, I use a default passcode 123456.

You should at least get the GAPBOND_PAIRING_STATE_COMPLETE with a timeout status if pairing never completes. Are you waiting long enough?
Are you ever prompted to enter a passcode on the Windows device? I would assume that this is required at some poitn.

It's impossible to comment more without some type of log. Can you post a sniffer capture as Marie mentioned? Or at least a Windows log of what is happening.

Thanks.

I'm waiting it until the Windows shows pairing failed. It never shows the passcode enter window. It won't hit the breakpoint on pairing complete, it only hits the pairing started. 

I don't have a sniffer now but I will get one soon. Here's the window of pairing failed showed on Windows. 

But it can be connected and read the device information and use the services on this device. 

And I print some log on console like below: 

WhenI click pair on Windows, the console shows paring started. After 3 seconds, it will show advertising again. 

Please take either an over-the-air sniffer capture or find a way to show the Windows log of what exactly is failing.

Is there any update here?

Sorry, I don't have any over the air sniffer. I will buy one ASAP. The only way I can use is to output the information from console, show as below: 

Is there any other method to find the problem?
