Radio disconnects

edited June 2020 in SmartSDR for Windows
Radio seems to drop out when left on with the latest beta upgrade, never had the this happen with previous beta so this may be a new problem. Radio is still on but SSDR can't see it, if I power cycle the radio it will show up. Flex 6500 here

    I just talked to Dudley on the Flex net and suggests that we do a reset on the radio. 
    With the radio powered off, press and hold down the “OK” button on the front panel of the radio. Momentarily press and release the power button to power on the radio.  Continue holding in the OK button until the front display counts down to 0, the power LED starts blinking white and the “CALIBRATING…” message is displayed, then release the OK button. Allow the radio to continue booting normally.

    I believe you should back up your profiles first? Probably already known but had to say it.

    I have been having it since the version previous to the Beta.  I have tried the reset but it seems to return after a week or so of being on.  Radio is 6300.

    So far no problems. No problems with VS 1.8 and just installed VS 1.10 a few hours ago. I run the rig and computer 24/7. I connect directly to my PC and do not use the DAX or Smart CAT functions. I am a CW only op. Sounds like a problem with the new added software stuff.

    I have had it happen the whole time I've had my 6500 and Maestro. It happens both with SmartSDR on my PC and on the Maestro, I'm not sure if it is the same issue on both. I've been using SmartSDR since version 1.8.4 and I've had it on all versions.

    For the Maestro issue I was told it was the radio doing a firmware reset and that Flex didn't know what the root cause was.

    1.10.8 was dropping out on occasion but now 1.10.15 working excellent.
    Left Maestro and 6300 on ALL weekend 48+ hours working a lot of DX in between.
    Gave it a good workout with no issues.

    Same problem here, but existed well before beta, over a year in fact. Factory reset, as described above, sometimes helps for a while, but being very awkward at the moment...up to 2 lost connections in 1 hour! Normally one lost every 2-3 days. I have a help ticket open on this and also trying various fixes....if I find a cure, I'll report back . 73 Rich

    Geez, with so many folks having the same issue, it sounds like it may be a buffer overflow or memory leak.

    All of you folks having this issue need to make sure you open a trouble ticket.  I don't normally leave my rig on for days on end, but I'm going to just to see what happens.  I'm still running v1.9.13 and not either of the Beta versions so it might not be a problem.

    Could those that have seen this problem report how long the radio was up and running until they saw the problem?  This may help us as we continue to look into this issue.

    Hello Eric, I did the upgrade the day the latest beta came out and when I did the upgrade I had turned off the radio per the release notes ( yes I do READ the release notes) and powered up the radio and it did it's firmware upgrade thing. And would have to say it dropped off about 24 hours later the first time and about 2 days later the 2nd time. I didn't do the factory reset yet even after talking to Dudley yesterday on the FlexNet because I want to see if it does it again. Maybe something will be in the log files that you can use if you would like to SSH into my radio.

    I let my radio run continuously and see a the disconnect about every 2-5 days.  As others have said you have to reboot the radio to reconnect.  Every so often I have to reboot the computer too, but that is a rarer occurrence.

    Thanks for the input.  How many computers do you run with SmartSDR for Windows on it?  I ask because we have identified and fixed an issue since the v1.10.15 release where the radio would crash after around 200 client connect/disconnect cycles (note that CAT, DAX and SmartSDR for Windows each count for one client each in addition any other clients -- SmartSDR for iOS, K6TU, DDUtil, etc).
