WiFi connects once after channel change.
lvu opened this issue · comments
Describe the bug
On the D1 mini board I got, Gravitymon doesn't connect to WiFi unless I change the AP's channel. After I do, it connects once, and then, after turning off and on, stops connecting again, until the next channel change.
To Reproduce
Steps to reproduce the behavior:
- Flash Gravitymin v 1.3.0 to a D1 mini with BrewFlasher
- Set up the AP name and password
- Try connecting, while watching the logs on the COM port; the results look like this:

- The connection gets established, until next time.
Expected behavior
Wifi connection gets established every time after powering the device on
Software:
- Platform: esp8266
- Version 1.3.0
Error 7 is probably due to incompatibility with your wifi network. Check the troubleshooting section for the needed preconditions for an esp8266.
All conditions are met. But the router is dual-band, with the same AP name for 2.4 and for 5 GHz – could that be the issue?
I have dual-band enabled on my UniFi router and that works fine with the esp8266 that I use. Might be some other setting that causes the issue.
The problem occurs in the underlying Arduino for ESP8266 library (or the hardware itself). You can check if the open issues might provide some clarity on what could be wrong. https://github.com/esp8266/Arduino
You could try some other project to see if that works? Does it work with the iSpindel firmware? Which version have you tried that worked? Could help to narrow down what the issue is....
This could be relavant; esp8266/Arduino#8956 or this one esp8266/Arduino#8950.
There are quite a few bug reports related to wifi.
I've tried the original iSpindel firmware, and it has the same issue. Actually, no version worked well. I've checked those threads, and the only suggestion there I saw was to disable the 802.11n mode on the router. I've tried to, and it worked... but only for the first time. Same picture: I change the setting (seems it doesn't have to be the channel), turn the device on, and it connects successfully. I turn in off and back on – and it doesn't connect, until I change some WiFi setting on the router again.
Could be related to the first issue i linked, band steering. If the router wants the device to reconnect that could cause the problem. What router model do you have?
I've tried with my main one, TUF-AX3000, and with a separate AP, RP-AC52 in AP mode. Turned 802.11n off on both devices; on the RP-AC52 AP names for 2.4GHz and for 5GHz were different.
I have some other observations, but I need to systemise them.
Its not an issue that i can handle unfortunately. It lies in the esp/arduino combination. You could try with the newer esp32 variants as they should have better compatibility. I support esp32c3 and esp32s2 mini currently and they have the same form factor as the esp8266
I've tried with ESP32 lite (the Floaty HW). Tried versions 1.3.0 and 1.2.0 of GravityMon, and with each one I get the same result: after saving the config and rebooting, the device seemingly doesn't try to connect to the WiFi at all. Probably I should file a separate issue? Here are the logs:

Can you try the 1.4beta its built using newer arduino versions
The wifi connection attempt should occur after the log that you posted... i.e. after the config file has been loaded
My bad. It was a hardware issue, the gyro was probably burnt.
