Is it possible to request all desired ODB II PIDs via a .dbc file?
问题 What I'm looking to do is request all desired PIDs via a .dbc file made in Vector db Editor++. I understand enough about CAN communication to be able to do this with 1 or 2 PIDs because the DLC allows up to 8 bytes of data per CAN message. I am also familiar with this resource on querying and responses of PID https://en.wikipedia.org/wiki/OBD-II_PIDs#CAN_.2811-bit.29_bus_format What I'm having trouble understanding is how diagnostic tools are able to query every PID the manufacturer of a
Communication with OBD-II using Windows Phone
问题 I have a problem with sending and receiving data from elm327 device. I tried to connect to the device using channel 01 (on Bluetooth) but it doesn't matter what command I send, I just receive the string "AT+BRSF=24\r" as an answer. I tried also to connect at channel 16 and there I receive a string "NO DATA" somebody knows what is the problem? thank you, Arie 回答1: The AT+BRSF=24 response sounds like you're communicating with the wrong Bluetooth device (perhaps a headset?). "NO DATA" sounds
Connect OBDSim to Torque on Windows through Bluetooth
问题 I'm trying to install OBDSim on Win7 but am running into some trouble. My end goal is to run OBDSim as a bluetooth ELM327 OBDII Simulator and connect to it using the Torque app on my Android device. I watched a video on youtube (http://www.youtube.com/watch?v=-dMjo5ySbcc) that demos exactly what I am trying to simulate but it was running Lubuntu 12.04. I've been reading through posts on mp3car and other posts on stackoverflow over the last week but I'm still a little lost. I'm not sure

Flow control message while receiving CAN message with ELM327

Send multiple OBD commands together and get response simultaneously
I'm working on application which connects OBD2 adapter and getting the real time data like speed,rpm,throttle position etc..When I read one command at a time, it works fine like by sending command "010C\r", I get current RPM. I think that sending multiple commands in one request is not possible.But in other applications like EngineLink HD ,Dashcommand, we found that multiple components are updated at a time like if we are driving the car and check the RPM,Sped and Throttle then they are updating at every 1 second. It looks like real time data. I'm surprised that how is it possible ? We have
