question

I'm running into a very similar issue, if not the exact same issue. I have been able to connect VictronConnect to my SmartSolar device in the past, but there are some times (including the present moment) where no matter what I try, I the app can't find / connect to the device.

Uploading my service report file in case it helps with narrowing down what might be happening.

Environment:

* macOS Mojave (10.1435)

* VictronConnect v5.7

* SmartSolar MPPT 75/15

When I open up console, I see several error messages that repeat indefinitely and begin pretty much as soon as I open VictronConnect:

default    23:09:27.350318 -0700    VictronConnect    {"msg":"CLClientIsLocationServicesEnabled", "event":"activity"}
error    23:09:27.350663 -0700    VictronConnect    #Spi, Invalidated

(Here's a gist of the same errors in case it's easier to work with)

Things I have tried. As far as I can tell, none of them have had any effect.

* Since a number of the errors in Console are related to location services, I verified that (1) Location Services in general were enabled and (2) searched for VictronConnect app in list of services requesting that Location Services access, but didn't see it listed

* Turning Bluetooth off and on

* Removing SmartSolar from list of devices in Bluetooth settings

* Turning off bluetooth on my iPhone (before using VictronConnect on my mac, I used the app on my iPhone for a few days).

I have not tried restarting my computer. Will give that a try now to see if that helps.

(this update follows up on my previous post)

Restarted, opened Console, and started VictronConnect again. Console isn't showing any errors this time. The output looks totally different. Still not connecting to the SmartSolar device, though. Get the spinning beachball for ~20 seconds instead like before.

    },
...
)

(as gist)

Even though restarting didn't fix things, it did seem to clear the error messages. It's interesting that the logs now mention "CBPowerManager". Maybe the issue is related to the computer going to sleep? It's a wild theory, but wonder if there's something there.

Update:

The SmartSolar device was listed about two minutes after I wrote the above update. Here's what I see in Console: (gist)

One thing that stands out in those logs is:

Sandbox: VictronConnect(1667) deny(1) network-bind*:1900
Violation:       deny(1) network-bind*:1900

I saw that _after_ I closed and reopened VictronConnect. Makes me wonder:

* .. is VC not closing a network connection?

* .. is there something else using that port?

Looks like port 1900 is associated with the Simple Service Discovery Protocol. Wandering back into wild theory territory.. this seems like something that may be needed for seeing a device?

Even though my device reappeared, I just tried closing and reopening VictronConnect, just to see what would happen. Alas, the device is no longer visible. So, whatever is contributing to the issue, seems like it can come and go pretty quickly. Again, makes me wonder if VictronConnect is the source of the issue (e.g. not cleaning up after itself like it should.)
