Unstable Wifi connection on 1.3.0 and ESP8266
misterdohl opened this issue · comments
Describe the bug
When putting the GravityMon into configuration-mode, it uses everything from 5-10 minutes to connect to the network chosen. When its in "ispindel mode" It doesnt seem to be able to report every 30 mins as configured. It often can go many hours inbetween reports.
To Reproduce
To be honest im unsure on how to report it, but I:
- Use reset-pins to get the blue solid light
- Connect to GravityMon wifi
- Configure my wifi (using the same wifi in both slots, ive also tried to put another wifi with invalid credentials in, but no difference)
- Press Save
- I see that the ispindle is trying to send/connect by the blue light blinking every 30 seconds.
- Eventually it comes online and i can reach it on a ip on the configured wifi.
When i then restart it/put it in a bowl of water it reports once (to brewfather), and then nothing. Last time i tried i had it connected for 2 hours without it reporting (every 30 min as configured).
Expected behavior
iSpindle should save and connect to wifi network within a minute. Should go to config mode when connecting charger and/or putting it flat on the desk.
Screenshots
If applicable, add screenshots to help explain your problem.
Software:
- Platform: esp8266
- Browser: Chrome
- Version: 1.3.0 (..b68835)
Additional context
I can add that both my Wifi hotspot and wifi password has blank spaces in them. I dont know if this can cause some issues?
Im unable to read any logs from my router due to my provider, so i cant verify if the ispindle tries to contact dhcp etc.
Tried to output "support information", but its stuck on "collecting support data, please wait"

From the logs it looks like it fails to connect to the wifi and then crashes due to failed connection.
I would suspect that there is something with you network setup that is incompatible with the esp8266, have you enabled 2.4Ghz ? Is the SSID broadcasting ?
Error 1 = No SSID found
Error 7 = Disconnected (failed to connect)
Can you hook it up to a serial monitor and get a dump of the serial log so I can see what is going on ? Just unplug the battery when you are connecting to the serial port of the esp.
Looks like this is looping throughout:

After looking into the specifications from espressif on the esp8266 these are some of the hardware/software limitations regarding wifi:
- Dont use space in your wifi SSID or wifi password
- Only supports 2.4Ghz bands, channels must be 1-13, other channels are not supported (In 802.11 b/g/n modes)
- Channels between 20-25 Mhz bands
From my own experiences:
- SSID must be visible (hidden SSID dont work)
Source: https://www.espressif.com/sites/default/files/esp8266_wi-fi_channel_selection_guidelines.pdf
I will add this information to the troubleshooting guide.
I reconfigured my 2.4Ghz to not have any spaces in either SSID or password, and it connected right away.
