I am having a problem with the GM862 device, basically it can respond to any AT commands, except comamnds related to python. ( I have also tried to reboot the device)

Thank you.

at#lscript

at#rscript

at#dscript

at#wscript

all fail.

at#lscript
+CME ERROR: memory failure

at#rscript="tracker.pyo"
+CME ERROR: memory failure

at#dscript="tracker.pyo"
+CME ERROR: memory failure

at#escript='…"

at#execscr

*** no response

Hi,

It would be a good idea to download “rsterm” from http://www.roundsolutions.com.

This is a hyperterminal program that also forms (at the push of a button) AT commands for:- making and receiving calls, sending and reading sms messages, reading the GPS, compiling and loading Python scripts, etc.

I write my Python scripts in PythonWin (to get syntax highlighting), I then use rsterm to compile them into .pyo form before I upload them (using rsterm) onto the GM862 module. I then issue the “enable” and “execute” commands using the buttons in rsterm.

I have the DTR low all the time while I do this.

It all works really well.

thank you, John.

I used GM862 Uploader in the past (which is written by someon in C#). One day I kept getting “write error” while using the uploader to download scripts, and the GM862 has been failing since then.

I can’t even use the rsterm now, I suspect that the memory has been already corrupted.

I wonder if there is any way to reset the memory ?

Thank you!! The issue is solved by updating the firmware. (thanks to telit technical support)
