Dear friends,

I want to realize a function that let CYBT-343026-01 to transmit data per 7s(Defult param), and somtimes can reset the 7s to 8s or 9s...

How can I modify the code with WICED-Studio tool which generated the code? Refill the high_duty_directed_min_interval&high_duty_directed_max_interval param in wiced_bt_cfg_settings and restart timer?

I think I need to realize the function same with "SAP,H=2BC0,D=0,F=2" in ezserial_343026-CYBT_343026_EVAL-rom-ram-Wiced-release.

BR,

Treacy

Hi Treacy,

From your previous threads, I beleive you are using ibeacon (broadcasting using adv packets).  From your description , I think you want to set the adv interval , so that your adv data will be in intervals of say 7s .

In that case , yes you need to change high_duty_min_interval / low_duty_min_interval / high_duty_directed_min_interval / ... min and max depending upon the advert mode you are using in the wiced_bt_cfg_settings

You don't have to restart any timer.

To change in run time, you may try changing the same structure parameter (like db_cfg_settings.ble_advert_cfg.high_duty_nonconn_max_interval = 11200;) before calling start advertisement.

Thanks,

Anjana

Just some additional comments for your question, there will be a random delay between the advertisement interval. It is a pseudo-random value with a range of 0 ms to 10 ms. You need to evaluate if it has any effect with your 7s precision.

Dear Owen,

Isn't  wiced_bt_cfg_settings struct the read-only object? I modify the code and complie, but it appear as below.

Hi Treacy,

Please change the const data type and try.

just wiced_bt_cfg_settings_t db_cfg_settings = {} in the wiced_bt_cfg.c and add as extern in your main app

Thanks,

Anjana
