Reach RS and LoRa 868/915 MHz radio

[RTK_Hunter]

This is a greater IoT issue as a whole, but would be nice if devices could communicate in standard protocol across the spectrum. Really extends applicability and integration possibilities.

No, it will not work with Reach’s LoRa.

I am attempting to do what you were trying in this post.

I want to make a Emlid LoRa compatible radio that outputs to RS232.

Here is what I have done.

LoRa Radio for 3rd party systems

That is actually opposite of what I am trying. I really do not need the transmit part, only receive for 3rd party systems. I know they do not want to cut their own throats by enabling 3rd party transmitting via a LoRa compatible. I am not trying to “under cut” them. Their M2 with their LoRa works fine as long as you are going Emlid to Emlid, I do it with my M2/RS2. I am trying to send Emlid RS2 RTCM via LoRa to 3rd party systems receiving corrections via LoRa. I can do it now with 3DR or R…

You got a little farther than I have. I just found your post this AM.

I know when the M2 is connected to the Emlid LoRa radio it is using 38400. I have put a T in the line and have it feeding both the LoRa radio and a RFD900. I have received corrections on my RS2 via LoRa and simultaneously a Trimble Ag monitor (FMX/FM1000) via a 3DR radio I attached to it.

I have not figured out how Emlid configures the radio. I know GPIO_0 lets the M2 know it is connected to the radio (from the documentation I am assuming it is connected to pin 5 of the radio, operation status). The M2 did not config it till I connected GPIO_2 so per the documentation pin 6 & 7 are used to config.

My next step is to monitor the communication from the different ports (RX/TX/GPIO_0/1/2). Hopefully, I can decipher what is going on to use a Nano to send configuration data to the radio and use it as a 3rd party receiver.

LoRa Radio for 3rd party systems

Did some testing last evening and this morning. Both the M2 and LoRa had their own power supply. I put a T in the M2’s TX line to a TTL to RS232 adapter which was connected to my laptop monitoring it with Realterm terminal program Hex/38400. At first all I got was garbage from the M2. I then remembered from the LM-210 design guide from Globalsat that all settings are applied at 9600 baud. I changed Realterm to 9600 and got data. I can now see which values change the freq and Kb/s. I do no…

jake.harders and DirtyHarry are you still out there trying to do this?

Sorry for the delay in replying. I don’t visit that often (obviously)

For my own gear, which is more or less standardised on existing Satel based radios I found it easier to change the one radio on the base to match those in the field, rather than the other way around. It just worked out easier for me that way.

I’ve just read through your other thread. Very impressive work and great tenacity on your part. Well played.
