Many difficulties to use RainMaker with basic examples (MEGH-4382)

[FernandoGarcia]

Answers checklist.

• I have read the Rainmaker documentation and the issue is not addressed there.
• I have updated my IDF branch (release/vX.Y) to the latest version and checked that the issue is present there. This is not applicable if you are using Rainmaker with Arduino.
• I have searched the Rainmaker forum and issue tracker for a similar issue and not found a similar issue.

General issue report

Hi!

I have found many difficulties to make RainMaker APP (V 2.10.1) connect to an ESP32-Wroover IE running the RMakerSwitch and RMakerSonoffDualR3 examples available in Arduino esp32 core 2.0.6.

Using a Galaxy J7 with Android 6.0.1 and switch example. Scan without reset immediately before recording and connection via BLE with reset in the middle:

I will add more information later.

Best regards

Galaxy Tab A8 with android 13 and RainMaker App V2.10.1 and ESP332 with switch example and Arduino ESP32 core 2.0.6

XRecorder_28022023_192051.mp4

Here the QR code scan doesn't worked. The WiFi scan when connected through BLE neither.

Placing the SSD and password manually in this video doesn't worked and I was getting the error 201 on serial monitor.

After watch the video above I have noticed an extra space at the end of SSID name and after remove the extra space it worked.

[JohnMacrae]

Yup! The extra space makes all the difference. I discussed this in some early videos https://youtube.com/playlist?list=PL4Um4E3Og2S8It9Dyhdvf3ScvuTA_Tp-i Hope they help reduce your frustration going forward 😊

[FernandoGarcia]

Hi @JohnMacrae !

This type of error is very common since the people is always using auto complete from keyboard.

The APP should make this type of filter to avoid users pull out some hair.

Best regards.

[fenilGhoghari]

Hi @FernandoGarcia ,
have you check your WiFi connection? and which ESP you are using?
also which ESP-IDF version you are using?

[FernandoGarcia]

Yes, with WiFi scan example the board can find dozens of networks around.

I'm using Arduino esp32 core 2.0.6 with Esp32-wrover IE.

[fenilGhoghari]

yes make sure when you send credentials at a time ESP connect with your mobile and you are providing right credentials else this is not generated my our end.

[FernandoGarcia]

What I'm showing here's that the App or framework are not working properly at Android 6.0.1.

App almost always can't find network with scan even with dozens of networks around.

App doesn't make basic filter as remove extra space at the end of SSID before send data to ESP.

The connection with QR code never works, I have always to send manually.

[fenilGhoghari]

idf.py menuconfig -> Serial flasher config -> Enable Octal Flash ON this settings can help you to generate QR smoothly

[FernandoGarcia]

I'm using Arduino IDE.

@FernandoGarcia Can you try the WiFiProv example and see if the same issue exists there?

[FernandoGarcia]

Yes, but it was connected at a second attempt.

With the code above there's no connection at all after reset.

[sanketwadekar]

As mentioned here, the Arduino WiFi library will try to reconnect only once if the connection failure reason is WIFI_REASON_AUTH_FAIL. You can manually check the WiFi connection status in loop() and reconnect to WiFi if status==WL_CONNECT_FAILED
