Buttons have no action (HW1.4 board)

[Marc--]

Hello there,

I'm having some troubles using the WifiDisplay Control with HW 1.4 board. The screen wakes up, and blink on 0:00. I can connect to the Access Point with my phone, but buttons have no action.

On the serial monitor, i can see the codes when buttons are pressed.

TEST_MODE is enabled, as i don't have a PSA head unit (and with TEST_MODE disabled, the screen doesn't wake up).

Is there a way to diagnose it ? Maybe a verbose serial log ? I don't have a scope, only a multimeter.

Regards,
Marc

Try uncommenting the lines from 98-100 in the main cpp. That way you can see on the serial monitor if the sent CAN messages are changing or not.

Thanks for your reply. I'm quite new to this, but i'm trying to understand.

Here is what i see with the "debug" on. A lot of messages from the display.

With the help of those 2 sites i can understand some messages:
https://github.com/prototux/PSA-RE/blob/master/buses/AEE2004.full/LS.CONF/
http://autowp.github.io/

But when i press a button on the phone, i can't see any CAN message. So i think my HW is faulty but... the screen wakes up, so it means the "ignition on" message is send on the BUS.

Sending "ignition off" when button is pressed makes screen blink, so data is send on CAN BUS.

        //radioButtonPacketSender->SendButtonCode(buttonId);
        uint8_t data3[] = { 0x0E, 0x00, 0x05, 0x2F, 0x02, 0x80, 0x00, 0xA0 };
        uint8_t data4[] = { 0x00, 0x32, 0x00, 0x1F, 0x00, 0x0D, 0x40, 0x01 };
        CANInterface->SendMessage(0x036, 0, 8, data3);
        CANInterface->SendMessage(0x0F6, 0, 8, data4);

I try to send "menu" : 0x3E5 40 00 00 00 00 00 directly without success.

I tested the version again, and it works on my side, so I am not sure what could be the problem :( But anyways I pushed a new version which replaced the CAN driver with the official one from ESP-IDF which is much more reliable than the previous one. Please try the new version, and see if it helps.
By the way which type of display do you try with? Can you post a picture?

[Marc--]

Thank you again. It's not better with the new version. My display is a type C "Johnson Controls" from 2012, bought from second hand market.

[morcibacsi]

Interesting... I have 2 Chinese type C displays and a Johnson Controls type A and all are working fine. Do you have another board to test (with this code, or for reading the sent messages with a CAN monitor sketch to check if the 0x3E5 CAN frame gets actually sent)

[Marc--]

I manage to make a "can reader" with a SN65HVD230 (finally a working one !!)

Quite funny ma car looks like a lab now.

I wire the listener first, then power the "wifi-can" module. Very strange but i don't see the "ignition on" frames 0x036 et 0x0F6.
No 3E5 either when pressing buttons.

My first thinging was: i'm not able to send messages on the CAN BUS.
But, i can wake the screen up. So messages are send.

Why i can't see them is the question i have to answer first. I'll do some experiments.

@Marc-- I am experiencing the same issue. Were you able to solve it?
