Connection problem



I just received today my first Wavecom GSM -module. I install all softwares and SDK’s, no problems.

But, Target Monitoring Tool shows “Arm exception aab a” and Terminal Emulator receives “OK” (+ 2 x ) in 10 sec interval, continously. Same thing if I try with Hyperterminal.

No response for any AT command.

Does anyone have any ideas what I should try?



Hi murjan,

It’s quite a while ago since you had reported this problem… Did you solve it?

Best Regards,



Yep, I did. I receive “special cable” (Boot and Reset switches) from distributor and with it I download firmware to device.
After that, it works fine.
