changing advertisement packet

[binhnguyens]

Hey, I have my nrf 52 dk. I have soft device v3 on my nrf 52.

I was doing a blinky test with two boards (one central and one peripheral)

I was just wondering how to change the advertisement packet? (customize my command in my ad pack or change my string) Via code or command prompt.

(the blinky test may not have anything to do with this)

Yes, you can change ADV and SCAN_RSP data with SoftDevice API, see GAP layer functions here (S132 V4, you can see very similar in other releases). You can basically call sd_ble_gap_addr_set, sd_ble_gap_adv_data_set and sd_ble_gap_tx_power_set any time to influence GAP advertising procedure, they will be effective from very next advertising packer (you can call it if it isn't advertising as well, then you need to call start to see the result, but you can call it even when it runs and no need to stop/start).

I recommend that you take a look at our Advertising tutorial, found here.

@endnode Can you give an example code of how this would be executed?

[binhnguyens]

is there an example that already contains all of this or something on github?

[endnode]

There are many examples in nRF5 SDK, simply download, unzip and search sd_ble_gap_adv_data_set in full text in all *.c files under ./examples folder. (to be honest it's pretty clear from linked documentation how to use that function, isn't it?)

@endnode I tried an example from nrf5 sdk, they include all the functions you listed. how do I change the actual packet (i have a sniffer dongle so i can read what is being sent, I want to be able to change the message) let me know if that makes sense
