M5STACK with ELMduino not working #179
Comments
Just compiled the ESP32_Bluetooth_Serial.ino example and it's the same output. |
Sorry, I can't speak Korean, but it should be relatively easy to update the example sketch in the linked website using the up-to-date examples given in the library. Best advice is to start with a working example from the library and work up to the level of functionality that you need for your project slowly. |
Neither do I 😅. |
Ah, I see. The only idea I can come up with is maybe the ELM327 is connecting not to your ESP32, but with another BT device (laptop, phone, etc) before the ESP32 can. Be sure to unpair every other device except for the ESP32 before turning either the ESP32 or the ELM327 or car on. Might even try a different OBD2 scanner. I've had ones go bad on me before. |
Its strange that I can use torque without any issue, and dont work with ESP32... |
Also when connecting it takes more than 10seconds to connect ESP to ELM, is this normal? |
Getting the same issue with the elm327 wired with the esp32 hardware serial. It flicks on searching and stopped and so on if i disconnect the elm327 from the car and plug it back in I get data instantly. Otherwise if I leave the elm327 working and unplug the microcontroller and plug it back in i'm back to searching and stopped. I am using it on a Honda civic 10th gen. |
any updates on this issue... is there a way to bypass it ? or fix it ? |
@hawkeye1103 i understand that right the Problem ist disconnect and reconnect ? |
The problem is it doesn't interpret the information until i unplug and replug the elm327 with the microcontroller still powered .... so it misses the connection start up protocol where it gives the commands: AT D, AT Z .... please tell me if I didn't explain clear I will try to explain differently. |
Hello,
First of all many thanks for this awesome lib, really want this to work on my ELM327 (I think it's a clone, not original, but works great with Torque).
I am trying to reproduce this example:
https://embedscope.com/125
Changed some stuff, since I think it's using an old version of the lib and myELM327.status no longer exist so replace with myELM327.nb_rx_state.
I cannot display any data, I've even removed all other and tried only RPM, but even then is not working, can anyone help me out?
I attach the debug log:
