OBD-2 UART Cant connect (EQC)
Posted: Thu Dec 02, 2021 12:08 am
Hi. Recently received the Mega Logger kit w/OBD-II UART Adapter, and have been uploading the most recent sketches and libraries according to the Developers Guide (link). The LCD screen output and serial monitor seems to indicate that MEMS, GPS and the SD card is working order, but the `.CSV`-files on the SD card and LCD monitor doesn't indicate any data being received. The SD card needed to be formatted as FAT32 prior to it writing anything, but not it at least gives empty files.
I'm testing this with my own vehicle, a 2021 Mercedes-Benz EQC (EV). It should be fully OBD-II-compliant but I'm unsure what the protocol is, or if there's anything else I need to do except plugging in the diagnostic adapter. Output is the same with ignition on/off. On one of the test drives, the 2nd screen with the RPM-stuff etc. showed up but without any values at all.
