PLS8-E ACM0 cannot use for AT command control | Telit Cinterion IoT Developer Community
May 19, 2017 - 7:56am, 1517 views
When I connect PLS8-E to my device and there are 4 ACM port which is ttyACM0 to ttyACM4. I can only use ACM1 for AT command control. ACM0 and other ACM cannot.
I have PLS8-E on DSB75 adaptor which can show ttyACM0 to ttyACM4 and I can use AT command through ttyACM0 and ttyACM1.
Please advise.
Thanks.
Hello,
PLS8 module offers two AT command instances MDM (Modem) and APP (Application) ports and NMEA streaming port. Please see AT^SSRVSET command in the AT commands specification document which configures the interfaces. The default service set (1) offers modem port on ASC0 and application port on USB1. Another predefined service set (2) offers the modem port on USB0 and application on USB1.
Best regards,

Hi Bartłomiej,
Thanks. I have changed to AT^SSRVSET to 2 and it works now. I have used AT&W to save the setting, is that correct?
Thanks.
Best regards,

Hello,
AT&W does not store the service set settings and is not needed here. Only a restart is needed to make the service set change effective.
