AT Command API for EHSx | Telit Cinterion IoT Developer Community

March 16, 2015 - 4:00pm, 3867 views


I'm currently porting a small Java aplication from a TC65i to a EHS5-E mode.

after modifying a few imports it appears to work, but I'm facing an exception when creating the ATCommand object.

According to the documentation:

5.8.4 AT Command API
Before using a new AT Command instance it should be reset (AT&F). Because of the employed
multi-MIDlet architecture another MIDlet may have used this instance before, but with a differ
ent setup, e.g. echo.

However, when I restart the aplication I'm always getting an IllegalStateException:

java.lang.IllegalStateException: openATCommand: no channel available.

I tried to run "at&f" command as suggested but i keep getting the error until I power off the modem and restart it from scratch.

Can anybody give me a clue why I'm having this issue?

Thanks in advance.


Hi, I got it to work by sending

resp = at.send("AT&F");
in the destroyapp() function.

I think  at.release() is what did the trick.
