Working with J-Link and J-Trace
J-Link WiFi setup
J-Link WiFi can be set up in multiple ways.
1) Using J-Link Commander:
- Connect J-Link WiFi to your computer via USB
- Start J-Link Commander (JLink.exe)
- Set up the SSID of your wireless network with the following command: SetWifi SSID <your_wifi_ssid>
- Set up the password to your wireleass network with the following command: SetWifi Pass <your_wifi_password>
- After a few seconds, J-Link WiFi should be connected to your wireless network (the green WiFi LED should be always on).
To get the IP address:
- After performing the steps listed above, issue the following command in J-Link Commander: USB
- J-Link WiFi will reconnect via USB and provide its IP address, e.g.: IP-Addr: 10.1.1.114 (DHCP)
- When connecting to J-Link WiFi later on via IP, use this IP address to establish the connection
2) Using J-Link Configurator:
- Connect J-Link WiFi to your computer via USB
- Start J-Link Configurator (JLinkConfig.exe)
- Right-click on the J-Link WiFi in the list of connected J-Links and select 'Configure'
- In the WiFi configuration section, enter the SSID and the password of your wireless network
- Click OK
- Unplug and reconnect your J-Link WiFi
- Click OK
- After a few seconds, J-Link WiFi should be connected to your wireless network (the green WiFi LED should be always on).
To get the IP address:
- Start J-Link Commander (JLink.exe)
- J-Link WiFi will connect via USB and provide its IP address, e.g.: IP-Addr: 10.1.1.114 (DHCP)
- When connecting to J-Link WiFi later on via IP, use this IP address to establish the connection
J-Link WiFi in J-Link Configurator
JLink WiFi will only be shown in the Configurator if connected via USB. This is because the Configurator uses UDP broadcast packets to find J-Links in the network. However, most routers have UDP broadcast and UDP multicast packets disabled for WiFi networks.
