LAN Connectivity Issue

Post by KE0DVW » Sun Sep 15, 2019 4:47 am

I recently moved my mmdvm hat to a pi 3b+. It is working fine. However, I want to use the pi's Ethernet port for communication with the internet, and the wifi connection for the radio. Has anyone done this, and can help me out. I am Steve KE0DVW. Thanks everyone.

I'm not following what you are asking...

Are you asking that you want two separate routes, one that sends any radio related traffic over wifi and then any other traffic like ssh or dashboard access over eth0??
If someones previous actions are any indication of their future actions, then I predict the deletion and removal of access will happen at any moment. 7-11-2020.

That's not how MMDVM hotspots are designed to work. The traffic between the radio and the hotspot is via RF. The hotspot handles sending digital signals to and receiving them from internet, either via a wired or wireless connection. The hotspot also handles all the conversion between analog and digital.

To expand on the previous reply... (incorporating frequency bands)

The MMDVM board runs on Amateur frequencies (2m, 70cm) if it has a low-power radio on-board (if one's board is controlling a pair of HTs wired to it, then the HTs control the frequency).

The WiFi runs on 2.4GHz (or maybe 5GHz depending on system) outside of the Amateur frequencies. It (or the hard-wired Ethernet) is used to relay traffic between the board and the Internet.

Radio <-- 2m/70cm RF --> MMDVM(or other) <-- digital packets --> R-Pi <-- WiFi/Ethernet --> Internet
