How can I evoluate my connection BLE to a pairing connection?

The passkey is randomly generated on each bonding, it is possible to also set a fixed passkey, you should find threads here on devzone by searching for "static passkey devzone" on google for instance.

My last question is : in the example glucose, where is generated the passkey (6 digits)?

I have an other questsion because in the example, the passkey is random? If I want to fix the passkey like when you unlock your phone, I don't understand how the passkey is created so how can I fix it...

ok, but if I don't want to allow this re-connection I need to manage the whitelist? It's the list with the different apparels?

You are only able to erase bonds on the BL652 that way, the phone may still have the bond and may thereby automatically re-connect.

Thanks for your help now I can put a passkey by how can I put the passkey at every connection because now, when I try to connect my phone, it etablishes automaticcally with the BL652? There is a memory?

Because I thought that this instruction " advertising_start(erase_bonds);" allows to erase mobile which tried to connect to the module, right?

Hi,

I think the answer depends a bit on which development environment you are planning to use. For instance since you are planning to use the BL652 I believe they have their own smartBASIC programming language:
https://www.lairdconnect.com/wireless-modules/bluetooth-modules/bluetooth-5-modules/bl652-series-bluetooth-v5-nfc-module

In that case you need to refer to Laird on how to setup and use passkey.

If you are interested in the Nordic nRF5 SDK, then there is one example for blood glucose example that show usage of passkey:
https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/ble_sdk_app_gls.html

Though I recommend to start with the getting started and read up on BLE before you start with that example.

Best regards,
Kenneth
