Hello,
I have programmed the ESP32 with the Blynk Edgent example using the Arduino IDE. When I apply power to the ESP32 board, the LED associated with WiFi provisioning does indeed blink. However, the Access Point does not show up in the SSID list of WiFi devices. It doesn’t show up on my laptop or my iPhone. What could cause this?
Pete,
Thanks for replying.
I did the “+ Add Device” thing several months ago, I was able to provision it via WiFi, and everything was working perfectly. Then there was a power outage at my house on March 14th, and it hasn’t worked since. So I replaced the ESP32, programmed it, and now I’m trying to provision it via WiFi. I’m using the “Reconfigure” option for the device in question. But when I do this, it says “No Device Found”. When I try it manually, I don’t see the Access Point (e.g. Blynk_xxxxx) in the list of available WiFi devices.
So in summary, I took known working software and programmed it into a new ESP32 board. Then I opened my existing Blynk app on my iPhone and did the Reconfiguration procedure, but no luck.
Don’t you think that this is information that should have been included in your first post?
What Blynk library version are you using?
Are you using iOS or Android, and what app version number are you using?
What do you see in your serial monitor?
I’ve been out of town and unable to reply sooner.
Yes, I should have stated that information in my OP, but I like to keep my posts concise and didn’t think
that info was pertinent to my issue, since I basically started from scratch with a new ESP32, programmed it with an Edgent based software, saw the led blink, but didn’t see the Access Point SSID appear in my list of available Wifi signals.
Anyway, to answer your questions,
Blynk library version: 1.2.0
iPhone is Apple (iOS): 3.5.4 (0)
The serial monitor shows that the ESP32 is continually rebooting. Before each reboot, it tries to connect to my router, which I think is incorrect. It should be providing an access point and waiting for an external device to connect. Am I correct? I can post the output of the serial monitor. Should I simply cut and paste the text into a post? Or should I somehow upload a file. I want to do it the correct way to avoid being scolded.
Below is the serial monitor output. It pauses after the line “[173] Connecting to WiFi: TDS1714”
for 2-3 seconds before continuing. FYI, TDS1714 is the SSID for my router.
Something else that you ought to have mentioned earlier.
Have you tried decoding the register dump data?
Are you using the Edgent example from the v1.20. Library with no changes other than adding-in the two lines of firmware configuration and un-commenting the correct board type?
Pete,
I solved my problem. The one thing I hadn’t updated was the ESP32 Board files via the Arduino Board Manager. Both the Blynk Edgent example as well as my IOT application are now working. Thanks for your help.
