PASSKEY

[katyon]

 I’ve downloaded     nRF5_SDK_11.0.0_89a8197 and starting with examples from \examples\ble_peripheral\???\pca10040\s132\arm5_no_packs\

 I would like the other device to request a passkey (constant) at pairing (the passkey on my side is constant - no display needed)

After   gap_params_init();I’ve added the following code:

 

{

 static ble_opt_t optS;

   static uint8_t passw[]="123456";           

 optS.gap_opt.passkey.p_passkey=passw;

   err_code =sd_ble_opt_set(BLE_GAP_OPT_PASSKEY, &optS);

}

 

err_code returned :  0  

 

Still the module will pair and communicate without requesting a passkey.

I've tried to find an answer in Q&A . in some answers there was a reference to fields : io_caps,mitm. cant make out what does it mean. 

(these fields belong to structs relevant to services, not pairing)

 

Thanks for any help

I tried to advertise manufacturer data. even coping a full function from Nordic help. for some reason- didn't work .

the application(cellphone) guy didn't like the appearance because he would have to preform a READ to get that info.

then I realized that the advertised Service isn't a real functional service. so advertising in is actually

"for free".

the app guy  didn't object so that's how we solved that.

so now a new issue.hope you still have some more patience left for my questions.

when trying to make the passkey work- you recommended to use ble_app_hrs example project .

(I'm using nRF5_SDK_11.0.0_89a8197 packege).

I've noticed but  didn't pay attention to it then:    the SW  RESETS every some time (~ 4 minutes) due to an error :   NRF_ERROR_SOC_POWER_OFF_SHOULD_NOT_RETURN returned by function sd_power_system_off   (called from sleep_mode_enter).

if I remove this function all together then the SW will not reset- BUT the BLE goes dead after the same time (~4 minutes).

meanwhile the SW is still running and the application timers are still on ( timers resulting from app_timer_create).

coming out of this situation - by resetting the HW/SW .

what would you say ?

thanks again

one more thing:

I've tried  using  nRF5_SDK_15xxxxx package  with ble_app_hrs example project.

its way too heavy . too many elements to remove (and than it gives some internal error).

so I still need your help regarding the resets/BLE dying .

I'd prefer not to call  sd_power_system_off if I can avoid it

Thanks

If you do not want the ble_app_hrs example to go to SYSTEM OFF, then simply comment out the sleep_mode_enter(); call under the BLE_ADV_EVT_IDLE case in on_adv_evt() and under the  BSP_EVENT_SLEEP case in bsp_event_handler().

me again, new issue 

now that a peripheral BLE is working (including the passkey), I'm requested to develop a tester for that unit.

For that I need A BLE central .

so I started with nRF5_SDK_11.0.0_89a8197\examples\ble_central\ble_app_multilink_central .

all is fine.the only issue is again: how to operate the passkey (as a central unit)

thanks

HI Yona, 

you need to reply to the BLE_GAP_EVT_AUTH_KEY_REQUEST with sd_ble_gap_auth_key_reply with the passkey as a parameter, see the Bonding: Passkey Entry, User Inputs on Central or OOB MSC.

You can also take a look at this post. 

Best regards
