According to the xDot developer guide, the xDot typically consumes 188 mA at TXP=20. This seems real high to me. The Sx1276 uses max 125 mA, the arm max 10 mA. Where comes the rest from?
Do I really have to design my battery to have a peak current of almost 200 mA?

no espace on mDoT ?
Hello, I just had my mDOT and the small dev kit with, but when I try to download a program, I have no space left, (0 ko) but there are nothing on my mDOT.. So i don’t understand why, do I have to buy another card with more memory to linkwith my mDOT?

When an mbed USB drive such as the mDot’s shows 0KB available that usually means that the mbed programmer chip could not communicate with the target. There should be a text file labeled “FAIL” in the root of the drive.
Are you using the MTUDK2-ST development board? If so you will need to connect the external power adapter before plugging in the USB cable.

Hello! I’m using MTMDK-ST-MDOT! And there was no external power adapter with this one!:/

Reply To: Install actility thinkpark on conduit aep
After the actility firmware is installed you will need to follow the mLinux instructions for flashing the firmware here: http://www.multitech.net/developer/software/mlinux/using-mlinux/flashing-mlinux-firmware-for-conduit/
You will need to extract the uImage.bin and rootfs.jffs2 files from the AEP bin. Simply treat the .bin as a tar.gz file to extract.

I think my mDOT has no programming header, but i’m not sure, and I don’t really understand what is this programming header.

Reply To: no espace on mDoT ?
Correct, the MTMDK-ST-MDOT does not require a power adapter. Does your mDot have the programming header installed? mDots with this header installed have a part number of the form “MTDOT-xx-X1P-SMA”. The header that should be populated is the one opposite the antenna connector.
If this header is installed, do the PWR and D2 leds come on when you plug in the USB connector?

Hi Jon,
If RN2483 has adaptive data rate enabled then why we need to set it manually?
Because we set it manually then I suspect it’s not enabled or there’s no support for ADR in firmware version 1.0.1 …. what’s your comment on this?

frame counter FCNY_GAP exceeded
In order to act in a good way i need to know what are the values of MAX_FNCT_GAP and MAX_FCNY_GAP used in the conduit AEP ?
In case fcny is exceeded, the standard says that subsequent frames will be discarded.
OK because it is a potential security breach.
But how is this handled by the conduit and particularly how do we get it back to work ?
To avoid having a sensor definetely discarded…
Thanks for your help.

Ok, I don’t have the programming header, I notice that the eight pins of the dev kit don’t touch the mDOT, it’s is easy to install manually?

Reply To: Access to LoRa node information via serial connection
The simplest method would be to use a MTAC-MFSER card. There is a node red output node for the MFSER module so the flow could be as simple as a LoRa input node, a function node that parses the message and the output node to the serial port. You can also interface to the serial port as you would any other at /dev/ttyAP1 or /dev/ttyAP2 depending on which accessory port you used. If you use the commandline you’ll need to set the mode using the mts-io-sysfs function described here:

Thanks Peter. Is the existing USB device port unavailable to do this type of operation?

Reply To: Access to LoRa node information via serial connection
The USB device connector provides a serial terminal so you could just use stdout there You’d need to handle the lora data as if you were on a mlinux conduit after installing the mosquitto mqtt pub/sub commands from the mosquitto-clients package. http://www.multitech.net/developer/software/lora/conduit-mlinux-lora-communication/
You can also try plugging in a USB serial adapter into the USB host connector, modules for some chips are available in the opkg feed. For example the pl2303′s module is provided by kernel-module-pl2303

Using the Conduit Debug port?
I have a mini USB cable connected to the debug port on the AEP Conduit and the other end to my computer. I don’t see anything flow thru’ the debug port.
I was under the assumption, the log.wrn,log.error that I write out in the node-red flow would show up via this debug port?
I have the set the log-level to debug on conduit settings, should I be increasing this to Maximum?
Thanks,
Yogesh

Yogesh,
The logging from Node-RED will come out in /var/log/app/node-red.log. The output on the debug port is the linux console output.

Is there a way to view this log from the conduit web admin or would i need to SSH into the conduit?

Reply To: Multitech Conduit Gateway 8 Radio Channels Configuration
Thanks Mike!
Well you are considering the following settings:
1. AEP Conduit version.
2. Network server configuration.
3. Using Node-RED to achieve MQTT messaging.
The question here, is Node-RED reliable enough to be considered for big LoRa network deployment, lets say thousands of end-devices? … can Node-RED be left running the application for two years without interruptions?
While my intention is to have the following settings:
1. AEP Conduit version.
2. Packet-forwarder configuration.
3. Messaging over MQTT protocol.
Hence, according to your answer in the previous message, I have to have a network server in between. Let it be my own network server to be installed instead.
Could you explain to me if the included MQTT library in network server configuration can be used under packet-forwarder configuration? … or I have to install new MQTT library to get the packet-forwarder configuration working to communicate to the application server?
Installing new libraries or software on Conduit gateway, is it recommended without affecting its performance?

Node-RED, file storage – read the data from it in javascript
Hi there,
I have got web socket listening to data sent by client. I can see this data on debug window by using debug node.
I would like to save this data to file storage. I know we can use file storage node. I did that, but how can I confirm that data is saved in it or not ?
Also, I would like to read the data from that file from the java script template and use within java script.
Any help would be great !
Thanks
