I have updated to R6.1 for WP7601 and Legato 17.9. The same code to connect WAS working under the previous release is no longer reporting that it has connected, but using the command line “cm data”, shows it IS connected. The response to le_mdc_StartSession is:

Also, the AT+SCACT=1,3 command succeeds with an OK, but it isn’t connected.
