Set public address(MAC) without BLE stack

[jayesh]

I am trying to write a radio code without using BLE stack here i was able to write down code for initialization of radio and was advertising some random packets. But how should i debug to know that am i advertising correctly or not. I tried to use sniffer for debugging but it was not able to detect it as i have not setted any public address(MAC addr). Do anybody have any idea how to set public address without using BLE stack. So that i can see adv packets on sniffer for that device. Or you know any other technique to debug the code, in-short to validate what i am doing correctly.

Hi,

You can see how it is done in advertiser_beacon.c in the hrs_advertiser example from SDK 8.1. ("..\examples\experimental_ble_app_multiactivity_beacon\hrs_advertiser....") Particularly the radio configuration part should be interesting.

If you have a spectrum analyzer or a software defined radio available you can check the spectrum for any impact when transmitting, note that this might be difficult due to WiFi or other in-band noise. Hopefully this answers your question.

Best regards,

Øyvind

Can you give me the link for that sample code.

Hi, the sample code is found in the SDK, extract this and navigate to ("..\examples\experimental_ble_app_multiactivity_beacon\hrs_advertiser\pca10028\s110\arm5_no_packs") where you will find the Keil project.

But this must be using BLE stack right... and i want to develop without BLE stack

This is using a timeslot between events where it sets up the radio as an advertiser without using the BLE stack.
