Accelerometer data advertising

[Ridhi]

Hi, 

I would suggest you take a look at Beacon Transmitter Sample Application or Direction finding connectionless beacon on how to advertise with data, and search for similar use cases on Davzone.

hi,

i know about the Beacon example and know about the advertising. But now i want to advertise the data of lis3dh accelerometer. pls assist me with some code that i can implement

Hi,

Max. advertisement time with the BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE flag is 180 seconds, see BLE_GAP_ADV_TIMEOUT_LIMITED_MAX . 

Do you get BLE_ADV_EVT_IDLE event after APP_ADV_DURATION is been expired? If so, start advertising following the BLE_ADV_EVT_IDLE event.

when i have i have:

 BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE; 

APP_ADV_DURATION to 18000 and 

static void on_adv_evt(ble_adv_evt_t ble_adv_evt)

{ uint32_t err_code;

switch (ble_adv_evt)

{ case BLE_ADV_EVT_FAST:

err_code = bsp_indication_set(BSP_INDICATE_ADVERTISING);

APP_ERROR_CHECK(err_code);

break;

case BLE_ADV_EVT_IDLE:

sleep_mode_enter();

break;

default:

break; } }

my device advertises for 3 mins.

BUT when 

changed flags to BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;

and APP_ADV_DURATION to 0 ; 

case BLE_ADV_EVT_IDLE:

 err_code = ble_advertising_start(&m_advertising, BLE_ADV_MODE_FAST); APP_ERROR_CHECK(err_code);

break;

default:

break;

but this way the device stops advertising.

What i need is that my device should advertise unlimitedly

pls help

Hi, 

Changing to BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE and setting APP_ADV_DURATION to 0 should advertise unlimitedly. You need to debug or check the debug log to see why BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE causes to stop advertising. 

If you use BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE, you can start advertising in the BLE_ADV_EVT_IDLE event.

I will be out of the office for the next few days and back next Monday. If you still have the issue, please create a new support case. Sorry for the inconvenience.
