Hi, I tested the library with an Arduino mega 2560 using Serial1 (Tx in pin 18) ang everything is communicating. Then I have switched to an nodemcu with the esp8266 and nothing seems to work, I've played with different pins and tried to use AltSoftSerial but nothing, same result with esp32 (Wroom-esp32).
I want to know if there's some special procedure when it comes to esp's or if I'm doing something wrong with my setup.
I'm doing all of this on my golf mk4 from 1999 so it's not OBD.
I can provide photos or schematics to make things more clear. Thanks for the help.
Actually I just have a simple request, I would like to query several blocks.
A query of all existing ones works, individual ones also work, but how can I, for example, query 4 blocks at the same time?
I think your work is fantastic!
This is exactly the lib I was looking for ^^
I just haven't figured out how to receive multiple blocks at the same time yet
hi there ive been working with your program and library for a few days here and been having trouble with the readings. try the 01 connection test i got everything to work just fine using there ALTserial for nano but when going into reading measurements or single measurement is doesnt seem to follow true. when changing BLOCK_TO_READ ILL normal can id is 0x42 for Control module voltage does not show. when i read into the https://www.blafusel.de/ for ids it says to use 66 for control module voltage but is still is not showing. ive tried 0x66 also just 42 and cant seem to get correct readings. would you please point me to what or how to fix this issue? i dont believe it has to do with the ALTSerial but im not going to say for certain. any help would be greatly appreciated thank you for you time and work!
I found that switching between ECU and Cluster modules (closing one connection, waking another module and connecting) takes about 12000ms from read to read. Is there a way to do it quicker?
