2.1.0 not working when 2.0.2 is

[wachl]

Szia! köszönöm szepen for this awesome project! I can't get 2.1.0 to work, serial output is just gibberish. 2.0.2 is working fine though! However my understanding was, that pressing the button on the pcb would activate the display, but it resets completly (at least at 2.0.2)?

Thank you for your help!

Hi! The latest release Is 2.1.0 which have features like turning off the reset function 30 seconds after boot🤓 Your problem is looks like to hardware issue to me: When you see garbage text on the serial the means you flashed the ESP with wrong flash mode

The resetting needs 10+ seconds pressing to the button so maybe a sticky button? Or the wrong flash mode problem causing this too

Hi! thank you for your quick reply. It was late last nigth and I screwed up the version numbers in my original post (already edited).

Still my issue is that 2.0.2 is working, only the reset pin is completly resetting everything and not turning the screen on. It is not a sticky button since I just short the pins manually.

I tried again to get 2.1.0 working (this time under MacOS) but it still wont work. I used this command to flash (ofc I erased the flash beforehand) esptool.py -p /dev/cu.usbserial-A50285BI --baud 115200 write_flash -fs 4MB -fm dio -ff 40m 0x0 rboot.bin 0x1000 blank_config.bin 0x2000 main.bin

And this is the serial readout after I joined the wifi and added to homekit: https://pastebin.com/6nBW4jR6

The screen stays off the entire time (working with 2.0.2). I think it might be an I2C issue?

The wrong flash mode sound interesting, however there is not much to do wrong rigth? I power the esp with the reset button pressed, release it, flash it and thats it?

Any help is appreciated!

What happens when you wait after the wi-fi connection? The Screen task is created 2 sencond after the successful wi-fi connection and HomeKit running

Until this try to dont touch the button

Unfortunatley simply nothing happens, no screen output and no serial output. It seems as if the ESP crashed.

It seems as if the ESP crashed.

can you send me an image of the connections how was the esp wired?

[wachl]

I am using your pcb :) (mini usb version)

Hi, I now tried using a different serial converter but I am still getting the same result. After flashing I restart the ESP (power off / power on -> no button press) and enter my wifi credentials through the webpage. The connection is established (I can see it connected to my wifi) but display stays off. Any other ideas?

I also tried this on three other air monitors I built, all behave the same way.

Thanks!

[HomeKidd]

On first setup the display should be on and it turns off after 5 minutes, so this could be a faulty display.

Did you updated the Fw to 2.1.0?

Did you tried to triple press the button for changing the display type?

Can you send a picture of the OLED screen?

[wachl]

Yes, I am using the Fw 2.1.0 I am using this SSD1306 screen atm which has the VCC and GND pin switched (for testing I am using cables and connect it properly ofc). Since I also think it might have to do something with the display, I have this SH1106 one (with correct pin layout) coming on monday.

The display is not defective however since it is working with fw 2.0.2. I would stay on that version but it seems unstable for me.

Thanks!

[wachl]

New display, same problem :( I also can not change the display mode, as soon as i press the button, the ESP restarts.Edit: Display Mode is changing correct, however display does not turn on. Any idea what I could try next? Thanks!

If I compare the behaviour of fw 2.1.0 vs 2.0.2 I think on the latest version the bus communication is broken.

Only bug on 2.0.2 i noticed is the resetting of the homekit configuration even on a short button press :(. On 2.0.2 display (only SSD1306) is working and sensor data is read.

Any chance you could send me the source code for fw 2.1.0 and 2.0.2 for me to check?

Nope, its still secret 😄

Only bug on 2.0.2 i noticed is the resetting of the homekit configuration even on a short button press :(. On 2.0.2 display (only SSD1306) is working and sensor data is read.

I'm still guessing that this button is broken. All my PCBs are running 2.1.0 and never have any issue like that. The reset code only runs when you press the button for at least 10 seconds. Also i have a lot of safety feature:

• first_init will prevent turning the display on when the SSD1306 task is not running
• _resettable will prevent resetting after 30 seconds from boot

void button_callback(button_event_t event, void* context) {
    switch (event) {
        case button_event_single_press:
            if(!first_init){
                lcd_power = !lcd_power;
                printf("HomeKid > Display %s\n", lcd_power ? "ON" : "OFF" );
                vTaskResume(ssd1306_task_handle);
                sdk_os_timer_arm(&display_timer, 300000, 0); // Auto OFF Timer --> 300 sec = 5 min
                save_states_callback(2500);                 
            }
            break;
        case button_event_double_press:
            break;
        case button_event_tripple_press:
            _is_ssd1306 = !_is_ssd1306;
            save_states();
            printf("HomeKid > Display Type changed to %s. Please Reboot!\n", _is_ssd1306 ? "SSD1306" : "SH1106");
            sdk_system_restart();
            break;
        case button_event_long_press:
            if(_resettable) reset_configuration();
            else printf("!!! HomeKid > Reset Failed!\n Reset can be done wihtin 30 seconds from reboot. Please reboot the device and try again!\n");
            break;
        default:
            printf("Unknown button event: %d\n", event);
    }
}

I've made some minor changes in v2.1.1 but i'm 100% sure that the cause of this problem is a hardware (button) related because the code never lets you fully reset on single press 😄
