Accelerometer data advertising

[Ridhi]

i have to advertise Lis3dh data. I have accelerometer and nrf52840 dk. Pls assist how can i advertise the data of lis3dh xyz values 

[Ridhi]

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??

Have a look at this case.

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?

[Ridhi]

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 

[Amanda Hsieh]

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.
