V3 standard build using WifiMulti fails to connect to Wifi reporting "Wifi credentials are not correct": Diagnosed as Auth Expire endless loop about esp32-miniwebradio HOT 16 CLOSED

Wolle,

I am very pleased to let you know, that my +Replacement ESP32N32R8 Devkitc-1 arrived this afternoon.
The issues with AUTH Failure is due to a poor antenna on the original. Similarly failure to raise an AP is likely to be the pooor antenna too.

I noticed that the original ESP32 would connect if I held a finger against the antenna, and disconnect when finger removed.

The salutary tale is that the market is flooded with poor quality ESP32 clones. On close inspect, it could be distinguished with the Boot and Reset buttons not in the published position.
I managed to find a genuine Espressif DevkitC-1ESP32N32R8, but not cheap at ~£23
On rewiring with my new DevkitC-1 Esp32N32R8, the radio connects quickly with a decent bit rate.
In addition it is worth reminding people that a decent power supply helps with WiFi Connection. I swapped mine for a decent 3Amp supply.

All I need to do now is:-
a) Figure out which setting is appropriate for the TFT
"20:13:49 Touchpoint not valid x=12, y=10
20:13:51 Touchpoint not valid x=14, y=13
20:13:53 Touchpoint not valid x=46, y=55
20:13:53 Touchpoint not valid x=14, y=25"

b) Insert the BBC Radio stations in the list.

I'm more than grateful for not only your efforts but also your patience.

Hello,
I have the following setting for ILI 9341

#define TFT_ROTATION 3
#define TP_VERSION 1
#define TP_ROTATION 1

This is how the touch works

from esp32-miniwebradio.

@RobinMosedale I have the same hardware config as you.
It connects to Wi-Fi (2.4GHz) and works ok, but I cannot acces it from the browser (laptop or phone).
I've used the wire connections from here: #338

from esp32-miniwebradio.

Thank you Arne65. I did manage to get it to log on twice and obtained the operation window and did something to touch. No more, so I'm not getting to the operational page any more

from esp32-miniwebradio.

IBBrz, The connections are now automatically generated by setting the processor, esp32N16R8, PCM5012 and ILI9341 (correct variant). They are nearly identical to your (MMC slightly different, but MMC seems fine).

What puzzles me is why the USB becomes unrecognizable when running, but fine in Burn/Boot mode. If I could get terminal output, I'd be able to see what's going on or inserting some serial messages

from esp32-miniwebradio.

If this happens: this is often a contact problem with the SD_MMC. Please check the wiring again, especially the solder joints. And if these resistors exist,

it is better to bridge them

from esp32-miniwebradio.

@schreibfaul1 It's the same for me, and I have an adapter soldered directly to the pins. I loaded version 2 and the logo is displayed correctly. The terminal displays this error:
[ 1164][E][tft.cpp:3782] decode_mcu(): pjpeg_decode_mcu() failed with status 29

from esp32-miniwebradio.

thank you, I was able to reproduce this, the MiniWebRadioV3.jpg image for the small displays is defective. I have replaced it. Please unpack the content_on_SD_card.zip and overwrite the file in SD_MMC /common/s

from esp32-miniwebradio.

Thank you Shreibfaul1,

Welcome screen now fixed. Therefore the MMC card has been reading successfully and not a contributor to any of the faults.

Double checked Router and Wifi settings, and all 2.4GHz, well within range. Default access point 30cm adjacent. Two successful logons last night, and obtained operational screen, with an IP of 192.168.1.212. Dunno where the 192.168.4.1 displayed comes from, not accessible and not identifiable on my network. Even with the 192.168.1.212 shown, unable to log on to the ESP32 webserver at that address.
Credentials wrong still displayed. 4 access points on the SD card.

Connection time increased to
#define CONN_TIMEOUT 8000 // unencrypted connection timeout in ms (http://...)
#define CONN_TIMEOUT_SSL 8000 // encrypted connection timeout in ms (https://...)
although I suspect that these having nothing to do with initial logon
Still no serial terminal activity

from esp32-miniwebradio.

Please replace the main.cpp with the example from Espressif. https://github.com/espressif/arduino-esp32/blob/master/libraries/WiFi/examples/WiFiMulti/WiFiMulti.ino Does this work?

There must be some fault in multiwifi

Suggest a simple wifi logon in main.cpp and I'll try it

from esp32-miniwebradio.

Looks as though we need a station close before retrying

from esp32-miniwebradio.

Re-emphasising issue with WifiMulti, fails to connect:

I have extensively checked the hardware under suspicion of it having a weak wifi receiver on another thread.

I have run tests back to back.

They are under Arduino builds as they are simple

The first is a simple WiFi.begin, with a time to connect:
The chip connects consistently in 500ms

The test is repeated employing the WiFiMulti.run() and it never connects

This seems fairly convincing evidence that on the same hardware, running in the same environment, within the same timeframe, one works, but the other fails. Does this suggest something odd with WiFiMulti?

If you would like further test runs or evidence to isolate please let me know
This is the simple wiFi.begin() programme

This is the output:

[WiFi] WiFi is disconnected
Time to connect - ms: 500
[WiFi] WiFi is connected!

Lastly, I'll attempt to replace the ESP32N16R8 with another. However, originals are hard to find in the Uk, most being a close clone
When achieved, I'll repeat.
A search of GITHUb throws up several references to WiFiMulti failingin a loop
