Hello,
I’ve been trying to compile and flash the “Body temperature thermometer” to an Argon and running into a bunch of errors. Is there a separate library I need to #include along with <Particle.h>? I copied the code from the example here https://docs.particle.io/tutorials/device-os/bluetooth-le/#examples
Image of errors attached, any help is appreciated!
Code:
#include "Particle.h"
// This example does not require the cloud so you can run it in manual mode or
// normal cloud-connected mode
// SYSTEM_MODE(MANUAL);
SerialLogHandler logHandler(LOG_LEVEL_TRACE);
const unsigned long UPDATE_INTERVAL_MS = 2000;
unsigned long lastUpdate = 0;
float getTempC();
uint32_t ieee11073_from_float(float temperature);
// The "Health Thermometer" service is 0x1809.
// See https://www.bluetooth.com/specifications/gatt/services/
BleUuid healthThermometerService(BLE_SIG_UUID_HEALTH_THERMONETER_SVC);
// We're using a well-known characteristics UUID. They're defined here:
// https://www.bluetooth.com/specifications/gatt/characteristics/
// The temperature-measurement is 16-bit UUID 0x2A1C
BleCharacteristic temperatureMeasurementCharacteristic("temp", BleCharacteristicProperty::NOTIFY, BleUuid(0x2A1C), healthThermometerService);
// The battery level service allows the battery level to be monitored
BleUuid batteryLevelService(BLE_SIG_UUID_BATTERY_SVC);
// The battery_level characteristic shows the battery level of
BleCharacteristic batteryLevelCharacteristic("bat", BleCharacteristicProperty::NOTIFY, BleUuid(0x2A19), batteryLevelService);
// We don't actually have a thermometer here, we just randomly adjust this value
float lastValue = 37.0; // 98.6 deg F;
uint8_t lastBattery = 100;
void setup() {
(void)logHandler; // Does nothing, just to eliminate the unused variable warning
BLE.addCharacteristic(temperatureMeasurementCharacteristic);
BLE.addCharacteristic(batteryLevelCharacteristic);
batteryLevelCharacteristic.setValue(&lastBattery, 1);
BleAdvertisingData advData;
// While we support both the health thermometer service and the battery service, we
// only advertise the health thermometer. The battery service will be found after
// connecting.
advData.appendServiceUUID(healthThermometerService);
// Continuously advertise when not connected
BLE.advertise(&advData);
}

buf[5] = 6; // Mouth
temperatureMeasurementCharacteristic.setValue(buf, sizeof(buf));
// The battery starts at 100% and drops to 10% then will jump back up again
batteryLevelCharacteristic.setValue(&lastBattery, 1);

Compiling CLI Command:
particle compile argon --saveTo ble.bin
here’s what I downloaded for for DeviceOS/SystemFW for 1.3.0-rc (attached), is there supposed to be argon-system-part2@1.3.0-rc.1?
