Define sensor ID In above setting, we have configure the sensor ID: sensor1,water,sensor3 and sensor4. Send data in pre-defined format Dragino runs a demon (IoTd) which will check all data get from its UART interface and check if it match this format:VALUE[.].

If it match, then the Dragino will store this values as the latest value of the sensor ID. Nbme step 2 ck pdf. It will store the data on local location or upload to IoT server periodically and then clear the data buffer. Examples of data format: • 8913367 • 1004378 in 1, Dragino will store: sensor1=89, sensor2=133 and water=67. In 2, Dragino will store: sensor1=100, sensor2=43, but no gas since gas is not a valid ID. Autodesk autocad structural detailing 2011 keygen download. Note: In the data format there should be one or more spaces between different sensor ID's. Transparent Mode Latest version of Dragino support Transparent Mode.

Nov 4, 2016 - local file = 'com3'; local serial = assert(io.open(file,'w')) serial:write('0,25,2,false') serial:flush() serial.close(). The problem i have is.

In this mode. Dragino won't do data validity in the UART port. It can receive any data comes from the UART port and store it. Write Custom Code Users can write custom code for UART for their own application.

In pre-load Dragino firmware, the UART port is used by the IoTd daemon (or pachubed in old version). You need to kill this daemon before testing your customized code, otherwise the test will fail. Run ps -av to find the daemon, in SSH access. While 1 do t = io.read ( ) -- read data from standard input (input in SSH) print (t ) serialout = io.open ( '/dev/ttyS0', 'w' ) --open serial port and prepare to send data to Arduino serialout: write (t ) --write data to Serial port serialout: flush ( ) -- serialin = io.open ( '/dev/ttyS0', 'r' ) --open serial port and prepare to read data from Arduino while line == nil do -- read data from serial. Line =serialin: read ( ) serialin: flush ( ) end print (line ) --print the data serialin:close ( ) serialout:close ( ) line = nil --clear the line data end to run this script.

Run root@dragino:~# lua write.lua //run the script lua 6 //input data to be sent to the Arduino I received: 6 // read the return data from Arduino.
