Re: Failed to read DTCs from two cars

Is the data from the co-processor the CAN data received? What does the "43" in the beginning mean? The wiki page describes that the service 03 returns 3 codes in each frame, 2 bytes for each DTC. So the first frame "43 00 00 00 00 00 00" Is all zeroes, three zero DTCs? The second...

Failed to read DTCs from two cars

I'm trying to read DTCs from two cars we have: BMW E61 2007 and Ford Focus 2006, but not getting any results. I added debug prints to the library functions and got following replies from the co-processor when connected to the BMW: readDTC sends: "03" from BMW receives: 43 00 00 00 00 00 00...

Re: Low power mode for OBD co-processor

The issue in my case was that when the ESP32 wakes up from light sleep it somehow triggers the SPI waking up the co-processor. Using following config for the sleep fixed the issue: esp_sleep_pd_config(ESP_PD_DOMAIN_RTC_PERIPH, ESP_PD_OPTION_ON); esp_sleep_pd_config(ESP_PD_DOMAIN_RTC_SLOW_MEM, ESP_PD...

Low power mode for OBD co-processor

As the OBD port power is always on, I want to have my ONE+ in low power mode when the engine is not running to save the battery. I have managed to get the current consumption down to 14 mA. It seems that the co-processor goes in to some low power mode roughly 20 seconds after the boot, if the Freema...

Source code for the CAN co-processor

Is the source code for the ARM CAN co-processor available? I bought the ONE+ model A assuming that this an open-source platform. Motivation: - I would like to check why is the sniffing functionality not possible on the model A. Is it a hardware limitation? - I would like to check why I'm getting a N...
