Hi,
I have problems with a number of devices intermittently disconnecting from the Blynk Cloud. To help troubleshoot what may be causing this I’d like to download the connection/disconnection logs for a device(s) from the Blynk Cloud Server (I will compare the events with my router/WiFi logs to see if there is any correlation of events).
Is it possible to download this data from Blynk Cloud Server for individual device(s)?
thnx

I was facing the same issue. The router was the culprit. Just replace the router if you have any or borrow one from someone. Else just factory reset the router and see if that solves your issue.
Disconnections have many reasons, this is just one which i faced.
If you have more than 32 devices at once connected to your router then it will drop one or more devices to maintain itself.
Thnx, I’m confident my router is fine, it’s only a few months, I’m not swapping/resetting my router, and therefore affecting every device in my house . . . I also have two WiFi extenders on my network, so having access to the logs I could match the times that devices connect/disconnect with other events on my router, the extenders or other issues.
I agree with this . . . that’s why the logs would be useful . . . another tool to assist with troubleshooting.

I dont know much about the wifi logs you are talking about. May be @PeteKnight can shed some light on this.
Meanwhile (a crude method) connect one of your devices to your computer and leave it. Later watch the serial monitor later.
Some times power supply will be causing the issue and harmonics(power line). ESP’s are very delicate piece of hardware.
Bill isn’t asking for the WiFi logs, he’s asking for the Blynk server logs from the cloud server.These would be accessible if he had his own local Blynk server, which he doesn’t.
I suspect that logging is turned off, or at least not set to a useable level on the cloud servers, to save space.

What do you feel about this solution ??
It doesn’t help at all. Bill has the data that he needs from within his own network, what he needs to see is the other end of the equation.

Agree Pete, thinking about it, any amount of meaningful log data for non-commercial users would be a huge amount of data, not really viable for millions of users. One day I may setup a local server, but the cloud meets my needs for now . . . and I await Blynk 2/.0 with baited breath . .
