hello there . i want to get i2c data on ble advertising packet
int main(void)
{
uint32_t err_code;
bool erase_bonds;
ret_code_t ret_code;
int16_t x_val;
int16_t y_val;
int16_t z_val;
uint8_t start_string[] = START_STRING;
ret_code = twi_master_init();
ret_code = ADXL375_I2C_init(&m_twi_master);
// Initialize.
APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_OP_QUEUE_SIZE, false);
uart_init();
buttons_leds_init(&erase_bonds);
ble_stack_init();
gap_params_init();
services_init();
advertising_init();
advertising_start();
conn_params_init();
printf("%s",start_string);
err_code = ble_advertising_start(BLE_ADV_MODE_FAST);
APP_ERROR_CHECK(err_code);
// Enter main loop.
for (;;)
{ printf("rushin");
ADXL375_I2C_acc_data_read(&x_val,&y_val,&z_val);
printf("X: %d \r", x_val) ;
delay_ms(100000);
delay_ms(100000);
printf("Y: %d \r",y_val);
delay_ms(100000);
delay_ms(100000);
printf("Z: %d \r" , z_val);
delay_ms(100000);
delay_ms(100000);
printf("\n");
power_manage();
}
}
in main function i am getting data.but now i want to get data on advertising function code is here
static void advertising_init(void)
{
uint32_t err_code;
int16_t x_val;
int16_t y_val;
int16_t z_val;
ble_advdata_t advdata; // Struct containing advertising parameters
uint8_t flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
ble_uuid_t adv_uuids[] = {{0x1234, BLE_UUID_TYPE_BLE}};
ADXL375_I2C_acc_data_read(&x_val,&y_val,&z_val);
ble_advdata_manuf_data_t manuf_data; // Variable to hold manufacturer specific data
uint8_t data[3] = {x_val,y_val,z_val}; // Our data to adverise
manuf_data.company_identifier = 0x0059; // Nordics company ID
manuf_data.data.p_data = data;
manuf_data.data.size = sizeof(data);
// Populate the advertising packet
// Always initialize all fields in structs to zero or you might get unexpected behaviours
memset(&advdata, 0, sizeof(advdata));
advdata.name_type = BLE_ADVDATA_SHORT_NAME; // Use short name
advdata.short_name_len = 6; // Advertise first 6 letters of name
advdata.flags = flags; // Set some flags. This is a topic for another tutorial
advdata.uuids_complete.uuid_cnt = sizeof(adv_uuids) / sizeof(adv_uuids[0]); // Create a list of UUIDs. This is a topic for another tutorial
advdata.uuids_complete.p_uuids = adv_uuids; // Create a list of UUIDs. This is a topic for another tutorial
advdata.p_manuf_specific_data = &manuf_data; // Load the manufacturer specific data into advertising packet
// Set the advertisement and scan response packet.
err_code = ble_advdata_set(&advdata, NULL);
APP_ERROR_CHECK(err_code);// Check for errors
}
here i want to data in uint8_t data[3] array. but my data is int16_t.on advertising packet i am getting constant data like Manufacture specific data:59-00-05-F3-FF. can you help me??
