Using advertising flags

[Nicole]

Hello there. I just recently started programming using the nRF52832 DK, SDK14.1.0 and SoftDevice 132 v5.0 . I tried to follow this tutorial on Github: github.com/.../custom_ble_service_example

Right after implementing my own custom service, the board was able to start advertising (indicated by the blinking LED1). Then I did one change to ble_advertising_init_t structure variable and wasn't able to advertise any more. More specifically, I wanted to change the flag content of the structure to use "BLE_GAP_ADV_FLAG_LE_GENERAL_DISC_MODE" instead of the given parameter "BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE"-

So why is advertising aborted/not even started when I change this component? Additionally, the flags' usage is not properly described in any documentation I found online.

Many thanks in advance! Nici

hi, try to modify this. #define BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE (BLE_GAP_ADV_FLAG_LE_GENERAL_DISC_MODE | BLE_GAP_ADV_FLAG_BR_EDR_NOT_SUPPORTED)

Hey, thanks for your comment, but what should I exactly modify here? I want to support EDR and don't know why this macro isn't working.

[karthikeyan]

did you modified your older BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE. to the new one i specified

It's already defined like this in my ble_gap.h.
