Am trying to use the old fashioned RTK with GSM. I use a GX1230 with Siemens M20 (GX1230 Tech Ref Manual lists M20 as a supported model). Connected the M20 to Port1, configured the Real Time Interface with Port1 and Siemens M20 that shows up by default in Smartworx with factory default AT commands. I create a Config Set for Rover, all done and Smartworx shows messages, 1. Config Set saved, 2. Port1: No response from GSM and 3.Port1: GSM Initialised. The SIM I use has both voice and data from the service provider. I do not have a Network RTK Infrastructure, so I am doing a Single Base to Single Rover RTK. Under Additional Rover Option, Accept Reference is "Any Received" and Ref Network is "None" (as I dont have a Network RTK Infrastructure).
Begin Survey, Press F3 CONEC, Screen shows Dialling 'mobile number', and immediately, it throws up 'Connection interrupted' error in Smartworx.
When I use AT commands on M20, I am able to call my mobile (rings) and from my mobile to the M20 unit, smartworx displays connection established. But its when I dial via smartworx, from Rover to Base, smartworx throws up this error almost immediately. Have struggled with it for 2 weeks.
Appreciate if you can throw some light. Thank you.
