Setup
I have used esp 32 wroom and car is basically suzuki vitara.
Error:
I have used single PID example and it works perfectly but when I use Multiple PID's example I am getting error ElmTimout error
screenshot is attached help me fix it kindly have studied all the issues but can't get my required one.
Anybody kindly help me out.
Which specific examples are you using? Note that "ESP32_Bluetooth_Serial.ino" uses Bluetooth for a single PID test and "multiple_pids.ino" uses HW Serial for the multiple PID test. So they aren't directly interchangeable with the same adapter.
@Shaikh010, I have added a new example sketch that queries multiple PIDs using the same type of BT connection as the "ESP32_Bluetooth_Serial.ino" sketch. Not sure if that's the issue you're seeing, but it may help others in the future.
@jimwhitelaw I have esp 32 module and obd 2 sensor it is showing correct data when using single Pid function but it shows time out error when i use multiple pid example code .
i just simply need multiple pids like coolant temp, engine temp, speed, rpm, abs load etc how may i get this data ?
@Bakar002 Are you using the multiple PID sketch I linked to above? If not, please post (with formatting) the sketch you are using and post the full serial/debug output to help us see what is happening.
@jimwhitelaw Have tried you new code why it is giving me wrong data and also give data in a very fast manner.Like when i connect it with esp 32 it connects but when it connects it gives serial data in a very fast manner and give wrong data
@Bakar002 please post the serial output so we can see what's happening. A fast response isn't an indication that something is wrong, unless every query results in '?' or 'NO DATA'.
@jimwhitelaw I am testing in Aqua and it mostly give me wrong readings why and its speed of response is also very fast. and also guide me that I am getting data through bluetooth and now how to get this data to any server or cloud because i have heard that both antennas dont work
I don't have any experience with Aqua. I'm aware that esp32 shares a radio between Bluetooth and WiFi, but I haven't had any issues with using both at the same time in any of my projects.
@jimwhitelaw
Thank u very much
Can you kindly share a code file or repository with me which in which we uses both radio at a same time
