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.

Regards,
Amand

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,

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.

I have followed this but when i increase my

I am trying to change

APP_ADV_DURATION to be more than 180 seconds but i am not able to do so.

I am getting advertisement data only for 3 mins not beyond that

RE: Accelerometer data advertising

Amanda Hsieh — Mon, 30 Aug 2021 08:54:31 GMT

You may do so by starting advertising following the BLE_ADV_EVT_IDLE event that is generated when the advertising module moves to idle.
Please see this ticket answer by my colleague.

The tool cannot be adjusted to present the float format in the manufacturer data field.

Gentle Reminder

Also, i want that my advertisement of lis3dh data to be indfinite duration. I am trying to change

APP_ADV_DURATION to 0

and BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;

but still my adverting gets stopped and no change is viewd kindly help

Hello,

thanku for assistance

i am able to receive the data of lis3dh in manufacturer data field. My issue is that i am receiving data in HEX format values. I want to view it in form of float. how to view?

Have a look at this case.

hello, am able to receive the data values in manufacturing packet. But i am only able to get x axis data kindly assist how to parse the values:

i have float LIS3DH_Acc[3];

these are the values i receive:

uint8_t tmp[6] = {0};
int16_t tmp_int16[3] = {0};
uint8_t status = 0;

//check data ready?
i2c_read(LIS3DH_I2C_ADDRESS ,(LIS3DH_REGISTER_STATUS_REG2), &status, 0x01);
if(status & LIS3DH_STATUS_REG_ZYXDA)
{
i2c_read(LIS3DH_I2C_ADDRESS ,(LIS3DH_REGISTER_OUT_X_L | LIS3DH_READ_MULTI_BYTES), tmp, 0x06);
tmp_int16[0] = (int16_t)((tmp[1]<< 8) | tmp[0]);
tmp_int16[1] = (int16_t)((tmp[3]<< 8) | tmp[2]);
tmp_int16[2] = (int16_t)((tmp[5]<< 8) | tmp[4]);

LIS3DH_Acc[0] = (float)(tmp_int16[0]) * LIS3DH_ACC_CONVERT_8G;
LIS3DH_Acc[1] = (float)(tmp_int16[1]) * LIS3DH_ACC_CONVERT_8G;
LIS3DH_Acc[2] = (float)(tmp_int16[2]) * LIS3DH_ACC_CONVERT_8G;

now, i have to put these values in data field of advertising packet manufacturer data

manuf_data.company_identifier = 0xFFFF;
manuf_data.data.p_data = data;
manuf_data.data.size = sizeof(data);

in this i want to put the data of LIS3DH_ACC how to put LIS3DH_Acc[0],LIS3DH_Acc[1],LIS3DH_Acc[2] values in data field??

I am able to set the manufacturer data with values of lis3dh in advertising mode. I am abel to get values

0x00010A this is the lis3dh data but i want that these acceleration values should be displayed in floating format

Please study tutorials:

Bluetooth low energy Advertising, a beginner's tutorial

Bluetooth Smart and the Nordic's Softdevices - Part 1 GAP Advertising

And refer to the examples to modify.

can u refer some example kindly where lis3dh data is advertised. I need some assistance for reference as i am new to it

RE: Accelerometer data advertising

Amanda Hsieh — Tue, 17 Aug 2021 08:01:32 GMT

You should refer to Beacon Transmitter Sample Application or Direction finding connectionless beacon to modify your project.

actually i have interfaced the accelerometer and am able to get data over ble via TWI. but this data is in connectable mode. But i want to display the xyz values in advertising mode for which i need your assistance

RE: Accelerometer data advertising

Amanda Hsieh — Mon, 16 Aug 2021 08:40:36 GMT

Hi,

We don't have the code as your requirements.

On a high level, you would implement this with some code that reads data from the sensor, for example via TWI or SPI. There are some relevant examples in the SDK, though not accelerometer specific. Then you would expose those data via BLE.

There are several similar cases on Davzone like

nrf52832-and-lis3dh-accelerometer

nrf52-twi-communication-with-lis3dh

nrf52-ble-beacon-with-accelerometer-data-advertising

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

RE: Accelerometer data advertising

Amanda Hsieh — Fri, 13 Aug 2021 13:37:55 GMT

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.
