How to detect authentified Central in range?

Anonymous · ‎Jul 07, 2017

Hello colleagues,

I set the GAP Role of my BLE device as Peripheral and Bonding Yes. When I connect for first time my PRoC to the Smartphone (Central) through CySmart App I can see all these events:

CYBLE_EVT_STACK_ON
CYBLE_EVT_GAPP_ADVERTISEMENT_START_STOP
CYBLE_EVT_GATT_CONNECT_IND

CYBLE_EVT_GAP_DEVICE_CONNECTED

CYBLE_EVT_GAP_AUTH_REQ

CYBLE_EVT_GAP_ENCRYPT_CHANGE

KEYINFO_EXCHANGE_COMPLETED. Here I can read the Long term Key: 10006aceca77f24d8755b800a0507258

AUTHENTICATION_COMPLETED

When I connect it for second time, the Authentification messages dissapear. What I would like is to know how I can know if one already-authentified Central is in range of my PRoC. I was thinking of reading SCAN_REQ Message and then compare its Long Term Key but I don't find such Event. How can I do this?

Thanks in advance for the great support!

Hi Peter,

Need some clarification.

When I connect it for second time, the Authentification messages disappear. - which message is disappearing?

You have kept bonding - yes, but did you called CyBle_StoreBondingData() API for store bonding? I suggest you to go through our Bonding example project for better understanding. https://github.com/cypresssemiconductorco/PSoC-4-BLE/tree/master/100_Projects_in_100_Days/Day015_Bon...

What I would like is to know how I can know if one already-authentified Central is in range of my PRoC. - Once after connecting and bonding, you can keep whitelist only that particular device. Please refer the following project :https://github.com/cypresssemiconductorco/PSoC-4-BLE/tree/master/100_Projects_in_100_Days/Day014_Whi...

Thanks,
Anjana
