Connectivity problem to target machine

I am able to connect to my Speedgoat target machine after target reeboot. But after running it for 10 min or more, connection is lost. I am using Matlab R2019b and Simulink Real-Time Version 6.11 (R2019b).

Here is the response from slrttest (after target has been running for a while).

### Simulink Real-Time Test Suite

### Host-Target interface is: TcpIp

### Test 1, Ping target computer 'TargetPC1' using system ping: ... OK

### Test 2, Ping target computer 'TargetPC1' using SLRTPINGTARGET: ... OK

### Test 3, Software reboot the target computer 'TargetPC1': Error using slrttest (line 160)

TargetPC1: Port is not open

Hi Mats,

Could you make sure that no other host PC or MATLAB release is trying to connect to the target? Are you using a direct connection, or do your target and host PC communicate via a LAN?

Best,

Dimitri

The setup is the simplest possible. Speedgoat alone connected to host PC using an ethernet cable. No other connections/computers.

Could you try running the following commands when this happens? Do you get your connection back?

tg = slrt;

tg.ping('reset')

Hi Dimitri,

Ping reset brings my connection back. Thank you very much!

BR, Mats
