Not able to open USB port and UART 3


#1

Hi all,

AT+WMFM=0,1,1 // OK for enabling UART1
AT+WMFM=0,1,2 // OK for enabling UART2
AT+WMFM=0,1,3 // ERROR (USB port Not able to open)
AT+WMFM=0,1,5 // ERROR (UART3 Not able to open)

I am able to open UART1, UART2 & USB CDC ACM but i am not able to open UART3.
AT+WDSO=0,5 (Trying to open UART3)
+CME ERROR: 3

Please give me some suggestions, it would be really helpful to me.
Thanks

Hi alex,
Thanks for response. I am working on SL8082BTA module. But i am not sure UART3 will support or not. But i got to know from sierra docs, UART3 is not supported to SL8082T.

Yes, as per PTS, UART3 is not supported in SL8BTA.
