For customers that wish to access Wireless Starter Kit (WSTK) or Ember InSight Adapter (ISA3) functionality through a firewall it is important to make sure that all required TCP/UDP ports are open for communications.
Below is a listing of all ports used by the ethernet backchannel firmware, used with the WSTK and ISA3 debug adapters:
|4900||Serial 0 / Virtual UART Pass-through||TCP|
|4901||Serial 1 / Physical UART Pass-through||TCP|
|4903||Reset Connections Port||TCP|
|4904||Time Service Port||TCP|
|4905||Debug Protocol Port||TCP|
|4920||Adapter Discovery Port||UDP|
|19020||J-Link debug/trace port||TCP|
Note that opening only a subset of these may lead to connection problems with Simplicity Studio.
