--get battery voltage value in mV
mv = api.getBatteryVoltage()

Schedules the next wake up event of the device to provided day of month (day), hour, minute and second. The provided wake up date is therefore absolute and not relative as in wakeUpIn().
--schedules next wake up to the 25th, 2:22:58
status = api.wakeUpAt(25, 2, 22, 58)
Schedules the next wake up event of the device after specified time interval. The provided wake up date is therefore relative and not absolute as in wakeUpAt(). Note: The input arguments are not limited, but the total period specified must not exceed 31 days. (e.g. hour = 40, days = 2 gives a period of 3 days and 16 hours).
--schedules next wake up in 1 day and 122 minutes

--set date and time
api.getTimeDate(2022, 1, 31, 24, 59, 0)

-- check if joined, if not join ...
api.loraJoin()
-- join!
api.loraJoin(1)
Sets parameters defined by strings s1 and s2.
This function resets previous activation settings. Meaning, if you call repeatedly api.loraSetup("ACTIVATION", "OTAA") it'll send join request each time this function is called.
“ACTIVATION” - Type of activation“ADR” - Adaptive Data Rate“DR” - Data Rate“DC”- Duty Cycle“OTAA-REJOIN-CONFIRMED-FAILED-COUNTER" - Sets number of confirmed messages after join reuest (cannot be lower than 5, which is also default number)"OTAA-MINIMAL-CONFIRMED-PERIOD" - Sets period of time (in milliseconds) to send join reuest (by default 7 days)"OTAA", "ABP""ON", "OFF", "GET"--set activation type as ABP
api.loraSetup("ACTIVATION", "ABP")

status,answer = api.nbSend("185.8.239.192", 5566, "test message", 6000, "UDP")
-- sends buffer to IP and port specified in GUI with 6s timeout
buf, err, proto, wake, ip, port, ctx = api.getGUIContext()
status,answer = api.nbSend(ip, port, "test message", 6000, proto)
Sends an AT command to NB module with specified timeout.
-- Get IMSI number of SIM card with timeout of 4 seconds

print("pin 3 set to:", api.DIOreadPin(3))
print("pin 4 set to:", api.DIOreadPin(4))
Returns temperature in milli degrees of Celsius (m°C) from DS18B20. In case of using multiple DS18B20 connected to one data pin, it's possible to address one DS18B20 with ID.
DS18B20 is functional after hardware changes. Also has to be allowed by the firmware.

api.ds18b20Search(1, 2, 3)
Reports current value of S0 channel counter (specified in channel input argument).
By calling this function, an internal shadow variable for the channel counter is updated, so that the counter for onThreshold() event is reset.
--Read the value of S0 channel 3 and stores to given variable (val)
val = api.S0readCounter(3)
Used to set the value of S0 counter in a non-volatile memory. Typicaly used on startup to restore current value.
--Set counter value for channel 0 to the value of 100
api.S0initializeCounter(1, 100)
Defines a threshold between current value of S0 channel counter and last reported value. When difference of these last two reaches the value, the onThreshold() event is called.
--Set threshold for channel 2 to the value of 10000
api.S0setThreshold(2, 10000)
Transmit "msg" and wait given "timeout" milliseconds for the answer. The transmission is retried "retry" times.

Use api.mbusState(1) before api.mbusTransaction() and api.mbusState(0) after to reduce consumption. The consumption significantly raises if the circuitry is turned on for too long.
Do not use the api.mbusState(1) during LoRaWAN or NB-IoT message transmition.
api.mbusState(1) --turn on M-Bus

Waits timeout milliseconds for data reception from RS485 bus.
Turn on RS485 using rs485State() function first.
After the first character is received the inter-character delay is 10ms. If the inter-character delay needs to be longer the function should be called again.
