Thank you all for your continued suggestions and assistance!!!

id also suggest you change DMR IDs by adding an ssid to each eg. 315070801 1315070802 (01) (02) this way the DMR server will see each installation as a seperate connection.
Thank you for this - I've had this configuration on DMR in place since last fall - so all is good here. DMR works exactly as I desire - being able to leave the mobile in my truck and able to operate on both without having to move the hotspots around.

Connect your mobile installation to the home network to check if your getting blocked by your mobile broadband service provider.

At this point I'd have to concur... Cable both up to your home router (just to avoid WiFi interference at first). Then try using each system from the radio (recommend not linking both to the same reflector). If you can link through both modules/frequencies when cabled to the home router, THEN
I like you suggest, I'm not sure why I would not have tried that before. Given my time to perform that configuration, I thought I would do one additional check to try to rule out any network issues with linking.

Linking / unlinking network test results:
With this test, I believe, we can rule out any network issues with linking and unlinking being network related.

Verification of config: Radio is able to link/unlink REF004C on home Pi-Star, only changing R1 / R2 settings.

Test: Attempt link from radio to REF004C from radio on mobile Pi-Star
Transmit: REF004CL to mobile Pi-Star
Result: Unsuccessful / no change
Observation: Log shows receipt of REF004CL, dashboard also shows receipt of transmission in RF section, but no link takes place

Test: Attempt manual link on Pi-Star using dashboard D-Star Link Mananger to REF004C on mobile Pi-Star
Result: SUCCESSFUL
Observation:
  • Log show successful link/unlink, dashboard shows successful link/unlink
    Radio receives Pi-Star "Linked to REF004C" and "Unlinked" when manual unlink is performed.

Test radios - I tested but Mobile Pi-Star configuration with both my ID-51a+2 and IC-7100
- both are able to link/unlink with the home Pi-Star, but not with the mobile Pi-Star
- both have two repeater memories defined in the D-Star repeater list
- Both radios are able to hear from and transmit voice on both Pi-Stars
- Both radios are able to receive digital data (show callsigns, etc) in the Msg: area
- Both Pi-Stars log the network header from both radios


Findings:
1. Mobile Pi-Star manual linking works
1.1 (I suggest) Rules out (network/firewall/layer 2) issue with Pi-Star connection to D-Star network
2. Issue remains with linking/unlinking from radio

Next steps??? Suggestions???
1. Is there more detailed logging for Pi-Star / D-Star that can be enabled?
2. Is there any logging that can be acquired from the backend / D-Star network to see what's being received from the Pi-Star?
If you know how I can accomplish the above, please comment.

Does this isolate the issue to being on the Pi-Star? Or, is this still a network traffic (hand-shaking/D-Star protocol)issue?


Thank you and 73s

Karl

If the attempts of linking with dstar manager actually result in both linking then theoretically that can only leave the radio setups between memories. Check and double check that each is exactly the same between the memory settings that link Vs the settings of the radios memory channel that doesnt link.

The only thing I notice is that your log does NOT show a "received RF header" for the link command. It shows that it received an INFO command header and end Tx, and THEN reports an end Tx for the link command, which has me perplexed.

(had to restart system as too much DMR traffic, and my default is for REF030C)

Re: D-Star Connection Issue with multiple hotspots - RESOLVED

I want to thank the Elmers who submitted thoughts and ideas, and most of all patience with pouring over the information I posted.

Those that pointed to the programming on the radio were correct.

I version control my code plugs and as was suggested, started from scratch only to find the following issue, once I compared a new working config with the old configuration.

The gateway need to be the correct callsign - K0EG::G {minus ":"s} and what I had accidently entered was the letter "O" instead of the number zero "0".

I don't know how many times I had looked at the entry, but it certainly didn't stand out. As a result I'm going to see if I can change the font in the system to address any future issues.

Thank you all for your help!
