APRS via Brandmeister with openSPOT4

DG1OBD

Hello,

I'm using an openSPOT4 with v84 and a Motorola R7 or Hytera HP785. APRS works perfectly via Brandmeister Repeater or MMDVM HotSpot (WPSD).
It doesn't work with the openSPOT4. How can I configure it?

Does none of you use this?

Have you looked at this?

Make sure the "Handle messages to/from source ID" is unchecked at the DMR SMS chat settings https://manuals.sharkrf.com/openspot4/en/side-panels-tools-page.html#dmr-sms-chat and then the openSPOT4 will forward data packets to/from the network. The APRS connector is not needed to be connected while using DMR as the BrandMeister server forwards your position data to the APRS network.

I use the OpenSpot with two DMR IDs: 2620649 and 2625850. The OpenSpot is registered with Brandmeister with 262064905. No APRS packets are transmitted.

Verify that you have the correct radio type setting on BM SelfCare for your ID 262064905.

HA2NON How can I configure self-care for an SSID 05? This only works with real DMR IDs.

DG1OBD

It's set to Hytera ID1 and Motorola ID2. See above: When I use an MMDVM or repeater, it works perfectly. It just doesn't work with the OP4.

These are not errors. Log shows that the openSPOT4 is ignoring the data call and forwarding the data packets to/from the server.

DG1OBD

Do you have another idea to my
APRS problem?

HA2NON

Look at the server's log for further info. Some servers expose their logs like brandmeister.hu

DG1OBD

What am I supposed to see? It works immediately via a repeater or mmdvm. Just not with the openspot. That costs time and nerves. I'm returning it, and the seller isn't responding to my email.

🙁

HA2NON

Maybe the server log will show you what's wrong with your configuration.

We've found your email in the spam folder, sorry about that. We will contact you in email regarding the return.

I tested the following:
BM Master 2621
Motorola R7
ID 2625850 doesn't work.
BM Master 2621
Hytera HP785
ID 2620649 works.

The openSPOT's SSID is 262064905.

It works if the DMR ID and SSID are the same.

How can I route both IDs?

DG1OBD

What's wrong with the configuration if it works on a repeater or an MMDVM?

HA2NON

The openSPOT4 does not handle any data frame differently if an SSID is used.

You can find the example transceiver configurations in the user manual at https://manuals.sharkrf.com/openspot4/en/example-dmr-confs.html#page-top

By the way, the screenshots are old. Hytera and Motorola have now released newer CPS.

Hello,

The openSPOT simply forwards DMR data frames to the server; it does nothing else with them. If APRS works with one of your radios, then our product is not faulty.

We are still waiting for your confirmation as to whether or not you will return the product.

With you, one of you doesn't know what the other is doing...

I know how to configure a radio. Read everything I've posted...
