PLS8-E ACM0 cannot use for AT command control | Telit Cinterion IoT Developer Community

May 19, 2017 - 7:56am, 1829 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.
