Slow / fast advertising

[oneguy]

Hi,

I have a question regarding fast/slow advertising

I'd like to advertise for 180s using a 100ms interval, then switch to a 1s interval, preferably for ever. I set advertise options as shown in the image.

When I test the software I find that advertising stops after 3 seconds. Why?

Thank you for helping me out on this M

Hello Kristin,

thank you for your help. I have found the following (refer to file ble_advertising.c, function ble_advertising_start, line 360):

if (m_adv_mode_current != BLE_ADV_MODE_IDLE) { err_code = sd_ble_gap_adv_start(&adv_params); VERIFY_SUCCESS(err_code); }

--> err_code is set to 7 (NRF_ERROR_INVALID_PARAM).

adv_params are set as follows: interval 1600 timeout 1000

By the way, we're using SDK_11 and softdevice 2.01.

Thank you again for your help!
