Hi, I’m using Open AT 3.13 and having trouble connecting to the device with Target Monitoring Tool.
In both Hyper Terminal and Terminal Emulator (when run from within TMT) I can successfully send AT commands and start software with WOPEN=1.
But TMT does not see the device. I see no traces (I did include them in my source).
It can not download any info about the modem. When I choose to autodetect the com port settings it responds “No Match”, yet I can send AT commands from Terminal Emulator.
Is your embedded application using the serial port?
If the embedded application subscribes the serial port, and switches it to data mode, it will not respond to TMT.
You need to allow a delay after your application starts and before it switches the serial port to data mode, and you need to do the TMT ‘Init Target’ in that time. Once the ‘Init Target’ has completed successfully, your application can switch the port to Data mode and the TMT will keep working…
