Problem step 3 Node.js about mkr1000

[RicardoMan]

yes, it is working with the //

[RicardoMan]

Hey Men , I Did!

update the firmware and also had to configure the file mkr1000wifi.js (maybe that was the problem)

https://www.arduino.cc/en/Tutorial/FirmwareUpdater

I will continue in the project, thanks buddy

[RicardoMan]

I want to thank you because it works perfect! the only thing I can mention is that the squematic is wrong with the light sensor with the soil moisture sensor.

My last question, if I wanted the temperature in Celsius, what file should I focus on?

The temperature sensor varies greatly in temperature, should I calibrate it?

Thanks again

[ryanjgill]

Awesome. Glad you stuck with it and got it going.

For the temperature change you would need to update the following function in app.js:

// get temperature measurement
function getTemp(tempSensor) {
  return Math.round(tempSensor.fahrenheit - 25)
}

to

// get temperature measurement
function getTemp(tempSensor) {
  return Math.round(tempSensor.celsius)
}

You can then replace all the spots where °F occurs with °C.

Its in a few spots in these javascript files: chart.js, tempDetailChart.js
and in a few pug templates: index.pug and temperature.pug.

As far as the temperature sensor calibration, mine was off by a large amount so I adjusted the value by subtracting 25 to get it closer to the actual temp.

I was thinking rolling back the node version would help but it looks like all the dependencies are having issues when I change the node versions. It fixes 1 but causes issues with another.

I'm gonna take a look later tonight when I get off work and see if there is anything I can do to get this project back up and running.

[RicardoMan]

thank you! I will be attentive

[ryanjgill]

@RicardoMan I've made some changes to the master branch. I was able to get it all working again with the latest updated dependencies. I did end up changing the static ip address since I've updated routers.

I'm using Node v8.16.0.

[RicardoMan]

thanks for the answer, now I improve everything, the only thing that when I generate the 'npm start' tells me the following:

Unable to connect! Please make sure you have the latest StandardFirmataWifi sketch loaded on the MKR1000

Is there something new that I need to change in the firmdata?

Thanks !!!

[ryanjgill]

That means the app is not finding the mkr1000 on the local network. To make sure you can connect to your network, you can uncomment the line in standardFirmataWifi sketch that will enable the serial console. In the StandardFirmataWifi sketch in the Arduino IDE you would uncomment this line:

/*
 * Uncomment the #define SERIAL_DEBUG line below to receive serial output messages relating to your
 * connection that may help in the event of connection issues. If defined, some boards may not begin
 * executing this sketch until the Serial console is opened.
 */
#define SERIAL_DEBUG

uncommenting that line allows you to view the console output in the Arduino IDE. I would uncomment that line and leave the static IP address setting in wifiConf.h commented out so it connects to your network and gets an IP address that is free. Then you can use that address as your static ip address and you would have to update the app.js to match your static ip.

You must comment out //#define SERIAL_DEBUG and re-upload the sketch for the app to work.

[RicardoMan]

apparently it is connected

StandardFirmataWiFi will attempt a WiFi connection using the WiFi 101 library.
Using static IP: 192.168.100.XX
Attempting to connect to WPA SSID: Rye
WiFi setup done
SSID: Rye
IP Address: 192.168.100.XX
signal strength (RSSI): -47 dBm

[ryanjgill]

perfect, now you can use that as the static ip and make sure to recomment out the serial debug line. You should only need to update it on the line here in app.js to match that ip:

// set options to match Firmata config for wifi
// using MKR1000 with WiFi101
const options = {
  host: '192.168.100.XX',
  port: 3030
}

[RicardoMan]

yes, modify the app.js with the static ip,

// set options to match Firmata config for wifi
// using MKR1000 with WiFi101
const options = {
host: '192.168.100.XX',
port: 3030
}

but it still says

Unable to connect! Please make sure you have the latest StandardFirmataWifi sketch loaded on the MKR1000

I will try to update my libraries

[RicardoMan]

What version of the firmata do you have on your arduino?

[ryanjgill]

its just the standardFirmataWifi sketch from the examples. it has this date in the comments at the top:

Last updated August 17th, 2017

[ryanjgill]

Did you make sure to re comment out line #define SERIAL_DEBUG in the standardFirmataWifi sketch and reupload to the mkr1000?

it should be //#define SERIAL_DEBUG.

[RicardoMan]

Well, I could not successfully achieve my goal, I tried many times everything mentioned and I could not connect to the server.

re install the matrix folder again and again, re install node, reset the arduino, update libraries, etc.

anyway I appreciate your support. Thank you.

[ryanjgill]

Sorry @RicardoMan. I feel like you are really close to getting it going. If you can see that the Arduino is connecting to your network, we just need to get the connection between the node app and the MKR1000 working. You should only need to match that ip for the connection to work.

Some of the problems I've ran across are networks not allowing peer to peer. Some universities and other public routers don't allow you to do peer to peer. If you are at home this probably isn't the problem.

Another problem could be that the Arduino is connecting to a different network than the computer running the Node app?

[RicardoMan]

if I use a different port? maybe port 3030 has it busy with another virtual machine

[ryanjgill]

Thats worth a shot, just make sure they match in the wifiConfig.h and the app.js.
