Hello,

I’m having a problem to start the app redSensorToCloud in my mangOH Red (WP7702). I followed all the steps in the Getting Started Guide, but we’re not using a GNSS antenna, we lost it.

I am not sure that is the problem, but here it go some possibilities:

When I initialize the app redSensorToCloud I get this issue, but I don’t know where to find the system log file:

_ **There was an error. Application ‘redSensorToCloud’ could not be started. Check the system log for error messages.** _

When I retry to initialize redSensorToCloud I see that the application is already running.

I didn’t find a compatible firmware and application for WP7702. So I left that one for WP8548:

_ **WP8548\_SWI9X15Y\_07.12.14.00** _

_ **SWI9X15Y\_07.12.14.00** _

When I try to connect, I get:

_root@swi-mdm9x28-wp:~# cm data connect_  
_Setting up profile 1_  
_Connecting … ok_  
_Cheking if device ‘rmnet\_data0’ is up … ok_  
_Routin inet … ok_  
**_mv: can’t remove ‘/etc/resolv.conf’: Device or resource busy_**  
_Testing connection … ok_  
_root@swi-mdm9x28-wp:~#_

The firmware version:

_ **SWI9X06Y\_02.16.06.00 7605a6 jenkins 2018/06/20 17:56:12** _

Bootloader Version:

_ **SWI9X06Y\_02.16.06.00 7605a6 jenkins 2018/06/20 17:56:12** _

Due this problem in the _cm data connect_ I can not connect with AirVantage.

So, my doubts are:

1. The problem with the connection could it be the by the absence of the GNSS Antenna?

2. What could I do to resolve that without the antenna?

Any help would be greatly appreciated!
