I notice a couple times a day my sensors stop sending MQTT messages and I have to reboot the mcGW to get them to start reporting again. Has anyone else seen this issue?

mc-Module / Light Sensor Demo
« on: January 03, 2018, 12:56:40 pm »
While following the light sensor demo, I keep getting a lot of false readings. For example, I place the mcModule120 in a closed drawer in complete darkness. It works fine for a few hours then every 30 minutes of so I get messages that the light sensor was triggered even through the drawer was never exposed to light. I noticed the same behavior on the reed switch. Any suggestions as to why? Any suggestions on how to resolve this?

mc-Things General Discussion / Integrating mcModules into schematic designs
« on: November 15, 2017, 09:52:32 am »
Iím looking into doing my own design for my sensors and have a question Iím hoping your engineers can get me started.

When Iím using a software tool like Eagle cad to design my sensor schematic, how do I go about integrating the mcModule into the schematic so that it shows up in the gerber files and is included in the BOM.

For example, there are library files on the internet that allow you to import the Arduino MCU into Eagle CAD and then you are able to select that component and drop it into your schematic, which is then included in the BOM and board layout.

Is there a way to do the same for the mcModules?

I have found manufacturers on the internet that will build your prototype design if you submit the gerber files but, Iím just wondering how do I get the mcModule included into those files.

MQTT / Sending Beacon Data Over MQTT
« on: October 15, 2017, 12:11:00 pm »
Is it possible to use beacons to send temperature and battery level data every 10 seconds over MQTT and still maintain 2 years battery life? If so, do you have any sample code that shows how to do this?

mc-Studio / mcStudio Error after Microsoft forced updates.
« on: July 19, 2017, 10:16:20 am »
Microsoft forced a windows update last night on my computer and now I get the attached error when trying to run mcStudio. I removed mcStudio and re-installed and was able to get mcStudio to start but, then when I open a new project the error came back. Any suggestions on how to resolve?

mc-Demo205 / Unable to Connect to the mc-Demo205

Beginning yesterday, I get the attached error every time I try and connect to the mc-Demo205. Any suggestions on how to resolve?

mc-Studio / Does mc-Studio Support Trig Functions?
« on: May 31, 2017, 10:04:27 am »
Does mc-Studio support trig functions such as sine (sin), cosine (cos), tangent (tan)...etc? If so, are there any sample code showing how to use them?

mc-Demo205 / Programming the mc-Demo205
« on: May 21, 2017, 05:54:40 pm »
Do you need to erase the current mc-script on the mc-Demo205 with OTA like you do for the mc-modules before you load a new mc-script or can you just connect the usb cable and overwrite the current script with your new one?

Is there a function or method in mcScript to determine if you are within Sigfox coverage?

In the sample code the GPS coordinates are encoded into msg using the AddFloat() function like this...


Upon receiving the data during the SigFox callback, how would I convert this back to a float value? Say like in php or javascript.

anyone have any suggestions?

mc-Gateway / Using WPS to re-connect Mc-GW to new Wi-Fi router
« on: May 01, 2017, 09:07:21 am »
Say I have my mC-gateway currently connected to my home Wi-Fi router but, now I want to move the mC-gateway to another location and connect to a different Wi-Fi network.
Can I re-connect the mC-gateway to the new Wi-Fi router by repeating the WPS process? (e.g. press the WPS button on the Wi-Fi router and then hold User Switch for 1 second)

mc-Innovations / Convert 3V to 5V
« on: January 27, 2017, 03:01:33 pm »
Looking at various sensors on websites I see a lot of sensors require 5V. Can anyone provide instructions on how you could use an MC-120 module with sensor that require 5V to operate? Is this even possible?

mc-Innovations / Car Battery Monitor
« on: January 11, 2017, 11:18:51 pm »
Can anyone provide some starting instructions on how one would go about using the MC-120 to monitor a car battery? Trying to figure out how I would wire the pins on the 120 to monitor the battery voltage level.

I just downloaded the new 120 firmware & mc-Studio and tried to program a couple of my 120 modules that were giving me connection problems earlier.

The good news is that all the modules are connecting consistently like before.

The bad news, when I try to "load and Save Program in Device", the popup window that normally told me the load was successful never appears and looks like mc-Studio is frozen. I have to close it via Task Manager.

mc-Module / Reed Switch Problems
« on: January 10, 2017, 10:18:45 pm »
I noticed that a few of my 120 modules fail to catch changes in the reed switch. I'm using the reed switch example that turns on the Red led when ReedSwitch is = true and turn it off when it's false. On some of the modules the led remains in the same state even if I move the magnet back and forth.

Are there any tips or tricks to be aware of when using the reed switch to make it consistent?
