CC2650MODA: Privacy 1.2, SimplePeripheral and ble_sdk_2_02_02_25

Gabohkiin

Part Number: CC2650MODA
Other Parts Discussed in Thread: BLE-STACK

Hello,

I am running SimplePeripheral in CC2650MODA and I believe I did the proper modifications as Developer Guide document for enabling Privacy 1.2

So far, this works OK:

I'm able to connect and bond with an Android phone (Moto E4 plus) using BLE scanner app
SimplePeripheral changes his BLE address every 5 minutes correctly.
I able to reconnect to SimplePeripheral with android phone after address changed.

However, if I reset or remove power from CC2650MODA and power up again, I am unable to reconnect.

Not sure what I am missing, isn't the following statements help to reconnect with the Android phone after reset?

uint8_t autoSyncWl = TRUE;

GAPBondMgr_SetParameter(GAPBOND_AUTO_SYNC_WL, sizeof(uint8_t), &autoSyncWl);

What other modifications do I need to do to SimplePeripheral in order to reconnect after reset?

Thanks in advance,

Gabohkiin

Hi Gabohkiin,

Is the device advertising after reset?

Hi Joakim, thanks for you reply.

Yes, SimplePeripheral is advertising after reset.

I did same testing with other phones (Galaxy Note 9 and iPhone 7) and noticed a different behavior: after reset the phones can connect to simplepheripheral but they attempt to pair again, I see the pair request pop up dialog again requesting the pair code (# 000000), what I think is that:

SimplePeripheral is not saving the bond information correctly to NVM.
SimplePeripheral stops resolving address due above.

Unable to determine what else do I need to enable to work correctly.

Thanks,

Hi Gabohkiin,

1. Can you post a sniffer log of the failed connection attempt?

2. Can you try re-connecting without re-starting the device? In this case, do the devices use bonding information or re-do the pairing?

Hi Marie,

Sorry, but I do not have a sniffer, therefore I can't provide a log.

In regards of your question #2: Yes, I can reconnect successfully to device (SimplePeripheral) without restarting it. Even more, after address change of simplePeripheral, the android phone is able to resolve sucessfully (I assume vice versa: the device is able to resolve the phone address). Apparently the issue is when I power cycle the device (simplePeripheral).

Thank you.

Hi Gabohkiin,

If you have an extra CC26x2 or CC1352 launchPad you can use it as a sniffer ( see

)

Can you use BTool and Host test to behave the same way as your simple peripheral, reproduce the issue and post the log from BTool?

BTW what version of Android are you using?

Hi,

Did you figure it out?

I will close this thread due to inactivity.

Hi Marie,

Very sorry, for my late answer. I still do not figure out, I will the test as you suggest using host test and BTool.

The version of Android that I am using is 7.1.1

Thanks,

I attempt to bond from my phone but unable to do so and the link has dropped. What do I need to answer to GAP_PairingRequested ?

Thanks

Hi,

It looks like there are a lot of events and commands BTool is not able to interpret. Are you using the BTool version buldled with the BLE-Stack? (Found in tools/btool.)

To complete the pairing you should answer the GAP_PairingRequested event. Please open the Pairing/Bonding tab.

Hello Marie,

The project's application end up not using Privacy 1.2 after all.

Thanks for the support!
