mc-Gateway / Re: McGateway not available in McStudio after setting MQTT settings
« Last post by Labmaster on November 27, 2017, 11:49:44 am »
I can see it now.  I had to update the application host portion of the gateway.  That was painful because I had to try 4 USB sticks to find one with low power requirements.

mc-Gateway / McGateway not available in McStudio after setting MQTT settings
« Last post by Labmaster on November 26, 2017, 05:18:13 pm »
I am trying to work through the temperature project on hackster that connects to WAI.io.  (https://www.hackster.io/mc-Things/temperature-monitoring-using-mcthings-and-wia-io-3ba7da).

The first thing I did was enter the Gateway config, and now I can't connect to the Gateway in McStudio.

I have the latest version of everything (Except maybe application host on the Gateway).  I can connect to the Gateway with OTA updater, but not McStudio.  I updated the firmware (to the same version, the latest).  I erased scripts and data store.

Tried Wifi and wired network (again, I can see it in OTA udpater, so I am on the right network).

Still can't see it in McStudio.

How can I do a factory reset on the Gateway

Kickstarted bundle with gateway 100 and 5 modules.

mc-Demo205 / Re: MC205 datetime.now() resets at boot time

Thank you MC-Abe, for your quick response. Please notify me when a technique is available to get the device to know the time from a GPS fix, because that will practical and accurate in our case. The idea was also generated here during a brainstorming session, so we're happy to help make it happen sooner than later. Any idea how we can help ?

Unfortunately there is no way to persist time on the mcDemo205 across a reset at the moment. We are working on improving this but the problem is trickier than it might appear on the surface.

As for your questions:
1. There is no such thing as a sigfox timestamp. All timing information is handled by the base station.
2. There are no plans at the moment to support sigfox downlink on the mcDemo205. The device is only certified for uplink by sigfox.

Another update coming soon is the ability to set the device time which on an mcDemo205 can be retrieved from the on-board GPS if a fix can be acquired.

mc-Demo205 / MC205 datetime.now() resets at boot time
« Last post by eric on November 22, 2017, 04:00:42 pm »
Problem: When the device is power-reset (jumper off-on), the shared function DateTime.now() resets to zero. Consequently any code running with reference to the time of the day becomes impossible to implement. In my practical configuration, the device is not connected nor connect-able to a gateway at that re-boot moment (it may be in the field by itself), however, it is in a Sigfox covered area.

Question 1: Is there a way to access the Sigfox time reference on board the device, so that the device can figure out what time it is ? My understanding is that when the device sends a Sigfox message, it sends a reference to that sigfox timestamp in the header (together with Sigfox ID) so that the sigfox network can calculate how many seconds have elapsed between device emission time and back-end notification time. Please correct me if my understanding is incorrect.

Question2: I understand the MC205 does not support Sigfox downlinks (messages from the cloud to the device) because of high power consumption. However, this could be used to anchor the device datetime reference after booting in the field, it would be only one message per boot cycle and could by itself justify making downlinks available ... Will downlinks become available in the future for MCdemo 205 ?

You just create the schematic symbol and footprint using the tool.

Yes, but how would I be able to get that into a PCB Design & Schematic Software such as Egale CAD.

I just started using this type of software so, I'm not aware of all the features they offer. Do these software packages usually have a built-in function to create your own components? Is that how I would go about it? Create the mc120 module manually and then choose it from the list of components to be placed on the board. Everything I have done so far has been using existing component libraries.

The module footprint and pin assignments are in the mcMod120 Product Specification which can be downloaded here:

mc-Things General Discussion / Integrating mcModules into schematic designs
« Last post by kbrooking 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.

Could you try it with Ethernet and see if the same behavior happens?
