OpenGD77 Hotspot testers needed

posted in: DMR, GD-77, Ham radio | 52

I have now integrated the Hotspot functionality from the Tier 1 version of the OpenGD77 firmware, into the Tier2 version, and I am looking for responsible beta testers.

I’ve been running the one of my GD-77’s in hotspot mode all day on BM TG91, which is normally quite active, and so far its working OK with no lockups etc

However at the moment I don’t think I’m confident enough that the firmware won’t crash and lock the radio while transmitting, so I do not leave it unattended and I also only have the power set to 250mW, so that even if it did lock while transmitting, it would probably not do any harm to the radio.

One other thing to note is that although the firmware operates in Tier2 mode, the radio only contains one transceiver unit, and hence does NOT operate as either a full repeater or even a duplex hotspot when in hotspot mode.
It only operates as a simple hotspot, like it did in the Tier 1 firmware.

In the longer term, it will probably be possible to make the radio operate as a single frequency repeater, where it listens on TS1 and transmits on TS2, but I will not be able to start work on SRF mode until all the major Tier2 bugs are fixed.

Anyway. If you are interested in testing the Hotspot mode in the Tier2 firmware. Please post a comment leaving you email address and I will try to email you the pre-release version

Update.
I’ve tested with BlueDV (BlueDV-9558) on the PC and it worked fine.

I’m not sure about the App versions of BlueDV. But I don’t have time to put a lot of effort into BlueDV as my main focus is PiStar and MMDVMHost on Linux or PC

Another update

There seems to be an issue where the radio (hotspot) is not receiving sometimes.

If you turn it on and it works, it continues to work, but if you turn it on and it doesnt work, try another the freq band e.g try 2m instead of 70 cm and vice versa

At the moment I’m not sure whats causing this

Yet another update.

I can’t replicate the Rx failure bug, however I did see some possible problems in the code, if anyone has set a different Tx and Rx offset value in the expert settings.

Under these conditions the Hotspot mode will not function correctly at all, and won’t transmit and receive behaves very strangely.

It seems that for some people Rx only works intermittently, but once it starts working, it carries on working until the radio is rebooted.

This looks like it may be caused by uninitialised settings, but quite what those settings are, I don’t know at the moment.

Hotspot Testers.

Please download the Tier2Latest file from the usual location, and use the same procedure as the version I emailed to you, in order to use Hotspot mode.

I have made some fixes to correct potential problems, however I can’t conclusively say that I’ve fixed the Rx problem.

    Hello Roger,
    I’m interested in testing. Most part of the day I’m stationary, first at the office and then at home. I have repeaters available for comparison purposes, but work with hotspots at both places, for comfort sake. I’ll put MD-380 on repeater and MD-390 on GD-77 hotspot. I have Raspberry Pi set for GD-77 hotspot since your first release, so I’m ready. 🙂

    Hi Roger
    I would like to help. I use an Openspot a Pi3 with Pi-star for the gd77 and a Jumbospot should arrive tomorrow. Should be FUN.

    I can beta test if you agree.
    I have presently 3 GD-77, one with official firmware, another one with alpha tier 2, and the third one is open to test (presently alpha tier 2 too)
    I mostly use two simplex jumbospots and the local DMR repeater which is on the top floor of my building
    I can connect too the third GD-77 to a pi 0 for the hotspot function. I did it with the beta tier 1 firmware, it is ready.

    Hi David I am willing to give this a try will also be using it on BM TG91 for my own use only. It will operate for at least 12 hrs per day attended (just in case it locks up). Thanks for all this marvelous work on the firmware that you have devised.
    PS Merry Christmas.

    Hello Roger, I’am still running the Tier 1 Hotspot since your first public Version, and I love it.

    I’am very interested in testing the Tier 2 Hotspot version.
    I’am running also the Tier 2 Version without HS on my second GD77.

    BTW

    I’ve been told it does not work with BlueDV.

    I will need to test this, as I’ve only tested on PiStar and on MMDVMHost on my PC

    I will run mine all day, but mostly listening.

    We should probably have our own BM TG e.g TG77 😉

    Concerning the Promiscuous Mode over both Timeslots (issue #61 https://github.com/rogerclarkmelbourne/OpenGD77/issues/61) I would suggest an additonal “any” timeslot selection, e.g. displaying “TS*” in the status bar. It seems the TX TS is already manageable by contacts’ TS overrides. Selecting a heard TG as TX override could also select the appropriate TS for TX.

    Another thing would be a direct mode operation option that would automatically TX in a free timeslot, e.g. “fTS”?, or “TS1f / TS2f” (try one first / two first), allowing for the flexible concurrent use of a frequency. (double capacity, pseudo / timeslot trunk mode, … that is simply like the daylight time sharing scheme on the globe)

    Hi David!
    I regularly use the latest Tier2 version as well as the Tier1 hotspot version without any problem.
    I’m ready to try out the integrated hotspot / Tier2 version on the BM TG208. My equipment is a Raspberry Pi 3B + and Pi-Star 4.10-RC6 software and, of course, a GD-77.

    Thank you for all the fantastic work on the firmware you have done for the radio community.

    installed .v.0.0.7 went fine. turned radio on per instructions in hotspot mode. the screen just said R 438.1000 no transmit like previously. and my other dmr radio receives from the gd-77 hotspot just fine. but when I transmit the gd-77 is deaf. the light on top of the radio doesnt even change colors. i have my offsets at zero. could I be doing something wrong?

    Hi Alec

    I’m not sure

    Is the Color Code correct ?

    Roger,
    I would be willing to test the new firmware. I do not run on Brandmeister at all but I do sit on the TGIF network. I do listen to TG 31665 but sit on TG 801. My self and Phil W7RSS both run the GD 77 hotspot mode. You can either email me or if you can get on the tgif network TG 801 and give a shout. k8upe

    Hi Robert

    I’ve found at least one bug with hotspot mode, where occasionally it won’t receive at all.

    So I’m holding off sending out any more for testing until work out why this is happening.

    Thanks guys, but currently I have 30 people testing, which is sufficient for now.

    Hopefully if I can get the bugs fixed, it won’t be long before I can do a public release.

    Hello Roger
    Unfortunately, the hotspot mode does not work as it should. After a successful connection with the DMR + server IPSC2-OE-DMO, the Raspi loses the connection immediately.
    The Pi-Star software still ran normally as if there is a connection to the DMO SERVER.

    Hardware: Rapberry Zero (latest version)
    Software: Pistar Pi-Star: 4.1.0-RC4.
    Otherwise the same settings as with my other hotspot.
    In the BM server of OE, the hotspot mode works without problems.

    tnx 73 de Christian OE3CQB

    Yes. I will test tomorrow again after QRL.whith the sys op from Server . Then i give you more Information.

    Good evening Roger,

    I’m trying with several colleagues, your firmware versions for more than a month with Pi-Star and MMDVMHOST(in Windows and Linux sistems) and we’re all satisfied with the progress you’ve made.
    I installed both the latest tier1 hotspot versions and the tier2 version, which I obviously have to load from time to time to test the functioning of the two configurations and I am therefore very interested in testing the tier2 with the integrated HotSpot function.

    A question …
    will it be possible to integrate the SCAN function in the Tier2 version in the future?

    Scanning is in the Issues list on Github, but bug fixes are prioritised higher than new features, and the project relies on me and other volunteers to give their time to programming the bug fixes and enhancements.

    The firmware is open source, so anyone can submit an update with new features, and it will be reviewed and added if it is acceptable.

    Bonsoir Roger,
    J’utilise votre Firmware depuis quelques temps déjà.
    Je suis très intéressé par le test de la version Hotspot de niveau 2.
    Vraiment très bien ce que vous faites,
    Avec tout le respect que je vous dois, merci de me faire parvenir la version hotspot 2.
