Pairing devices S130

[nejcokle]

Hi,

How could i implement Just work pairing method in my "ble central and peripheral" example. I modified project to suit my need, and everything works fine, untill i try to write to peripheral. I figured out i need to set pairing method "just work". Is there any easy way to implement this method?

@nejcokle: Please let me know which firmware you are running on the peripheral peer device ? Did you use the ble_app_hrs for S110 ?

I don't think pairing is required for that example. However, if you want to implement Justwork pairing, you can have a look at the ble_app_hrs_c for S120, at hrs_c_evt_handler() function where we trigger bonding at BLE_HRS_C_EVT_DISCOVERY_COMPLETE event.

Sorry for late response. I'm using Cypress ble module as my peripheral (will get nordic ones soon) and i use nRF51822-mKit as my central. As i can see on cypress example it requires "just works" pairing method. As my central i'm using dual role example. Is there any other way to implement this pairing method? Also, when not paired i can read char values just fine.

@nejcokle: Are you using the mKit as an mbed board or you are using it with our SDK example ? Which exactly project are you testing with ?

I don't think there is other way to trigger bonding other than calling sd_ble_gap_authenticate() as we do when calling dm_security_setup_req().

I'm using project "experimental_ble_app_s130_example_c__s130_pca10028" It's that dual role project. I'm asking if there's another way to bond because in this example you don't connect to device using DM. So if i have to use dm i think i'd have to change a lot of the project.

@nejcokle: I'm sorry I was confused with the ble_app_multilink_central and ble_app_multilink_peripheral where we use the device manager. But the principle is the same, you need to call sd_ble_gap_authenticate() to trigger bonding. And if you want to rebond later on you need to store the ble_gap_sec_kdist_t that you got after the bonding has finished ( BLE_GAP_EVT_AUTH_STATUS event).

We have an example for S130 that use device manager here.
