The J-Link WiFi comes with native WiFi support. For detailed information on how to setup the J-Link WiFi, please refer to this article.

Via WiFi bridge

This method is possible with the following models:

• J-Link PRO
• J-Trace PRO

The J-Link PRO and J-Trace PRO models have an Ethernet connector for wired Ethernet. Therefore, making these models accessible via WiFi can be achieved by simply using a WiFi bridge.

1. Setup a WiFi bridge for the desired WiFi network.
2. Power the J-Link PRO / J-Trace via a 5V USB power supply (e.g. mobile powerbank).
3. Connect the WiFi bridge to the Ethernet connector of the J-Link PRO.

Via J-Link Remote Server

This way of WiFi-enable is supported by the following models:

• J-Link BASE
• J-Link PLUS
• J-Link ULTRA+
• J-Link PRO
• J-Trace PRO

The easiest and most commonly used method to do so is by using a Raspberry Pi (RasPi), running the J-Link Remote Server.

1. Start the RasPi and connect it to the desired WiFi network.
2. Install the J-Link Software Pack on the RasPi and the remote PC (available on the homepage).
3. Connect the J-Link to the RasPi via USB.
4. Start the J-Link Remote Server on the RasPi and use it to connect to the J-Link.
5. Install the J-Link Software Pack on the remote PC that is supposed to connect to the J-Link.
6. From the remote PC connect to the J-Link Remote Server on the RasPi as described in the J-Link Remote Server article.
