Hi, I have a commercial Blynk project. I have a customer that keeps getting this message while trying to provision: “Configuration error.” What could be causing this? I have many devices all around the country that have been provisioned without any issues. I even sent him another device to see if it was a problem with the device. But the same thing happens. Could it be something with his router? With his network provider? Any help would be greatly appreciated!
The hardware is a custom esp32 based board, and I am running blynk edgent and using dynamic provisioning.
Good questions. It’s the same template I’m using for all my customers, so same name. Unfortunately I use a stand alone programmer for the board. If my customer wants to attempt it, I was going to send him a programmer so he could get me a screen shot of the serial monitor. I haven’t asked him about his SSID or password. I didn’t know there were limitations there. Is that based on the preferences library? What unusual characters are you thinking could cause a problem? Also, do you know where I can get more information on the “action codes” in the picture I attached above? I cant find anything on Blynk’s website or documentation about them. Thanks Pete!
Those are just numerical presentation of actions, i.e. 74 - was creating new token for a device. It is the last command before app drops server connection to talk to the device. After that we see app reconnected to server (2 == login) and tried to fetch that device (apparently without success).
Hard to tell more without logs (hardware and/or app). Very often it is just incorrect wifi credentials entered by user.
I have been getting this error more often recently I have also found that things are running much slower. Not sure if it is on my end or not, It was very quick to re provision
but now takes a while and fails very often.
If I wait until I see the device wifi then it works better. It looks like it is taking about 20 seconds per call to the blink edgent.
