Hello folks,

I am using cc1354 Bluetooth chip for Bluetooth communication and we observed following issue could please support for following issue what we observed,
we are facing a BLE issue in passive entry. When we checked the issue, the phone is not able to read the Gatt characteristic from the TI board, after bonding. During owner pairing, when it is still not bonded, the device is able to read this characteristic. But once it is bonded on further connections, the device is trying to read the characteristic but NOT able to read that, in most of the cases. Very rarely it's succeeding.
We have tried a third party app with the same use case, to check whether it's an issue from the phone's Digital Key side or not. We are seeing similar behavior there also

Thanks and regards,
Prashant

Hi Prashant,

1. Which version of the SimpleLink SDK are you using?

2. Can you capture a sniffer log of the failed and succeeded reads?

https://dev.ti.com/tirex/explore/content/simplelink_cc13xx_cc26xx_sdk_7_41_00_17/docs/ble5stack/ble_user_guide/html/ble-stack-5.x-guide/debugging-index.html#packet-sniffer

3. What kind of device is your peer device? (Another TI device? A smart phone?) Which one is the peripheral and which one is the central?

Cheers,

Marie H

Hi Prashant,

I didn't see a connection in the packet sniffer log. You might need to configure the packet sniffer to follow the connection. Please see the link I posted.

Cheers,

Hello Marie,
Is TI hardware is mandatory? Or the TI software will work with any other BLE hardware?:

Hi Prashant,

If you mean the Packet Sniffer, then yes you need a TI LaunchPad to run the FW.

You can find other Bluetooth LE sniffers on the market, any one should be fine.

Hello Marie,
we captured sniffer log from wireshark

data_for_Ti.pcapng,sparkmindaashokmindagroup-my.sharepoint.com/.../EU10XtnqzgtCsQnk9lOS-uwBaCFiW2vXrvrbzyfCl1qqpQ

CC1354 macid (Gatt server) :- d1:6e:43:b0:f3:40
Android device macId (Gatt Client):- d4:3a:2c:bb:d5:d2

Test Sequence:-

1. Connected unbonded device
2.Read Gatt characteristics (Working)
3.Bonded with Ti Board
4.Recoonected device
5.Gatt Connnection failing.

Hi Prashant,

Can you tell me the packet number where the connection starts?

I'm only able to see ADV packets etc in the log. no packets from d4:3a:2c:bb:d5:d2.

Hello Marie,

I have shared the link for ADV Packets data in this log. Please find the same and revert back.

Hi Prashant,

I don't want the ADV packets, I want the packets that are sent in the connected state.

You told me you have an issue with the GATT characteristic discovery. This process happens after the devices have connected so I need to see the connection packets in order to see where the process fails or stops.
