S120/S130 scan, getting client device friendly name

[Florin]

Hi all,

I am using S130 in scanning mode and I would like to list the devices that are currently advertising by their friendly name. I have access to p_ble_evt via BLE_GAP_EVT_ADV_REPORT but I'm stuck trying to find out which field in the nested structure holds the BLE client friendly name.

Any help is appreciated! florin

Have you tried the adv_report_parse() function found in the ble_app_hrs_c S120 example in SDK 7.1.0?

I haven't tested it myself, but hopefully you can use it with the appropriate BLE_GAP_AD_TYPE_DEFINITIONS, for example BLE_GAP_AD_TYPE_SHORT_LOCAL_NAME or BLE_GAP_AD_TYPE_COMPLETE_LOCAL_NAME.

Please add a comment if you get into trouble.

Hi Petter, sorry for the late response. The scan doesn't receive any of the definitions you've listed. I'm getting the following:

BLE_GAP_AD_TYPE_APPEARANCE
BLE_GAP_AD_TYPE_FLAGS
BLE_GAP_AD_TYPE_TX_POWER_LEVEL
BLE_GAP_AD_TYPE_128BIT_SERVICE_UUID_COMPLETE (I'm broadcasting a 128bit uuid)

I have access to the ble_evt_t data structure and I think the friendly name is buried there somewhere. The struct is quite nested and gdb freezes in its attempt to list it. I can give you more details if needed.

Are you sure you have a name? I have just tested this with ble_app_hrs and ble_app_hrs_c and it seems to be working fine with BLE_GAP_AD_TYPE_COMPLETE_LOCAL_NAME. Could you test with those examples first? Please see the ​Core Specification Supplement (CSS) v5 for information on the format of advertising data.

I'm pretty sure the BLE_GAP_AD_TYPE_COMPLETE_LOCAL_NAME doesn't get broadcasted. What's interesting is that the BLE device scanner apps do display the friendly name. I'll try, with ble_app_hrs, thanks for the advice. florin

Yes. I used the adv_report_parse() function, and get the device name. It's works.
