ALL AT COMMANDS

Postby kanthed » Thu Jun 01, 2017 6:54 pm

Need a list of all AT commands for GSM, GPS and OBD. (For freematics one with sim800l so that I can write my own code).
Also AT commands to send and receive RAW CAN signals.

Google ELM327. You'll find the AT commands there. That is the chip the freematics unit uses to read OBD2 data. for GSM/GPS, it's in the code. You'll have to figure that out.

I don't see an ELM327 anywhere on the board. From what I can tell hes got code in the STm32f103 to emulate a ELM327. This is all fine and dandy, but not all the AT commands are supported :x ... The following AT commands would have helped develop code, but are not supported and therefore pretty much prevent me from developing with hardware anymore.

Stanley, some questions ... how can I change the delay for CAN responses? I tried the following AT commands with no success:
ATST <--- this is the one I need!!! The rest were found to not be function either.
ATFCSH
ATFCSD
ATFCSM
ATCFC
ATBD
AT0 1-2

I need to know if this is an accurate description of what could be wrong with changing delays in CAN RX so that I may adjust our project timelines. Please get back to me.
Thank you.

Oh sorry I didn't know you were talking about the emulator. I don't know anything about that.
