Advertising data

hi. I refer at the example find here link text.

i want to transmit with Advertising, as the temperature is transmitted in the example, data from some sensors . But in the example i can transmit only a uint8_t data.

    uint8_t battery_data = battery_level_get();
uint32_t temperature_data = temperature_data_get();

service_data[0].service_uuid = BLE_UUID_BATTERY_SERVICE;
service_data[0].data.size    = sizeof(battery_data);
service_data[0].data.p_data  = &battery_data;

service_data[1].service_uuid = BLE_UUID_HEALTH_THERMOMETER_SERVICE;
service_data[1].data.size    = sizeof(temperature_data);
service_data[1].data.p_data  = (uint8_t *) &temperature_data;

I want to transmit a float variable or uint32_t or uint16_t.

Is it possible?

How can i do this?

Thank you for your attention

Thank you for your reply.

if I have more sensors can I create custom services? for example instead of BLE_UUID_HEALTH_THERMOMETER_SERVICE

BLE_UUID_AMBIENT_LIGHT_SERVICE

or BLE_UUID_X_MOTION_SERVICE?

how can i do this?

and how many service can i put in the advartising packet?

can i make something like this?

ble_advdata_t advdata;
uint8_t       flags = BLE_GAP_ADV_FLAG_BR_EDR_NOT_SUPPORTED;

ble_advdata_service_data_t service_data[6];


service_data[5].service_uuid = BLE_UUID_X_MOTION_SERVICE;
service_data[5].data.size    = sizeof(X_MOTION);
service_data[5].data.p_data  = &X_MOTION;

service_data[4].service_uuid = BLE_UUID_Y_MOTION_SERVICE;
service_data[4].data.size    = sizeof(Y_MOTION);
service_data[4].data.p_data  = &Y_MOTION;

service_data[3].service_uuid = BLE_UUID_AMBIENT_LIGHT_SERVICE;
service_data[3].data.size    = sizeof(LUMEN);
service_data[3].data.p_data  = &LUMEN;

service_data[2].service_uuid = BLE_UUID_BATTERY_SERVICE;
service_data[2].data.size    = sizeof(battery_data);
service_data[2].data.p_data  = &battery_data;

service_data[1].service_uuid = BLE_UUID_HEALTH_THERMOMETER_SERVICE;
service_data[1].data.size    = sizeof(temperature_data);
service_data[1].data.p_data  = (uint8_t *) &temperature_data;

service_data[0].service_uuid = BLE_UUID_OBJECT_TEMPERATURE;
service_data[0].data.size    = sizeof(OBJ);
service_data[0].data.p_data  = (uint8_t *) &OBJ;


memset(&advdata, 0, sizeof(advdata));

advdata.name_type            = BLE_ADVDATA_FULL_NAME;
advdata.include_appearance   = false;
advdata.flags.size           = sizeof(flags);
advdata.flags.p_data         = &flags;
advdata.service_data_count   = 6;
advdata.p_service_data_array = service_data;

err_code = ble_advdata_set(&advdata, NULL);

thanks for your patience
