What settings do you have on conduit?

[Jose Olvera]

-The Conduit and the LoRa have the same settings
which is BAND1, 915Mhz, netname= testnetwork
-The DEV KIT came without the 5V Power Supply, and the only power comes from the USB cable

[Brandon Bayer]

Jose,

If you can issue AT commands to the mDot, your UDK is powered properly.

Please post the output of the AT&V command from the mDot as well as a screenshot of your Conduit’s Lora configuration.

PART 2 : QUERY the setup … looks OK
NOTE: the ‘RESET’ … does not seem to do anything ? no LED blinking
NOTE : the firmware upgrade was saved …but…. after power cycle …the LED turns RED, and I need to reload the firmware and wait for LED to turn GREEN

What version of Conduit firmware do you have?

[Jose Olvera]

THE CONDUIT FIRMWARE WAS UPGRADED TO …LATEST … 1.0.33

[Brandon Bayer]

Jose,

Ok, so we still need to see either a screenshot of your Conduit lora configuration or post a copy of /var/config/db.json

-Brandon

[Jose Olvera]

Note: I am an RF engineer (I am not an ‘network’ engineer) and some of these tools used by your systems are new to me :

– I failed to do a simple copy/paste screen shot (png file), the system does not allows me to ‘paste’

– How to copy/paste here the….. /var/config/db.json

[Brandon Bayer]

Jose,

Alright, let’s just have you go ahead and create a support case which will make it easier to help you and send files back and forth. Use the same login information as for these forums and in the case, describe as much as possible. Put what you have tried, what works, what doesn’t, etc. Also include either the Conduit configuration files or screenshots.

Thanks!

-Brandon
