Chad,

Thanks for the reply. That was what what I was leaning toward also after swapping out for a few different antennas.

I found a company in San Fran doing some testing where and their gateway and antenna were on a rooftop as well.

Thanks,
Tom

Hi,

I have been having range issues as well. I have the dev kit with the mDot and Conduit and standard accessories (antennas). With the TXP set to 20 and SF_10 on the mDot. I have power set 26 on the Conduit running version mLinux 3.1.0, with AEP version 1.0.33, but I am only seeing approximately 1200 feet, non-LOS.

I performed the tests with the AT commands.

WITH antennas:
at+ping
5,8.8
at+rssi
0,-2,0,-1

WITHOUT antennas:
at+ping
-96,7.8
at+rssi
-96,-96,0,-33

Can you tell me if my module is OK? If it is, what could be the problem? I am in an industrial park with the gateway at my desk. To get the measurements, I placed the mDot in my car and drove further away until packets dropped.

Thanks,
Tom

Hi Brandon,

Yes, it makes total sense now.

And I have tested it and it works. If you set the payload in ‘inject’ node it will send that payload. However if you leave it blank in ‘inject’ it will send the payload from the ‘lora out’ node.

Thanks for all your help. I’ll now be able to begin my range testing.

Thanks,
Tom

Brandon,

Thanks for the tips, I was able to use the logs to determine that I was receiving the entire time.

What I was confused about is that the payload was always the ‘echoed’ payload of the original message from my mDot, NOT the payload in as set in the ‘lora out’ node of Node-RED, which the ‘info’ on that node describes.

Does this make sense? My guess is that it’s an ACK. However is there a way to send a ‘new’ message as a response from the Conduit or is this how the system works?

Thanks,
Tom

Hi Brandon,

Thanks for the quick response. I have tried doing the AT+SEND (without data), also the EUI with colons and I still don’t RX any data.

I’ve also tried having the ‘lora out’ node both connected and disconnected from the ‘lora in’ node to see if that has any effect and it did not.

Is there perhaps a step I’m missing on the ‘Node-RED’? Or perhaps am I missing something for the configuration on the mDot?

Thanks,
Tom
