Question
How can we verify whether the watch’s network connection and port xxxxx are open and accessible from the PC?
Short Answer
Use ipconfig, arp -a, ping, and telnet commands to confirm that both the PC and the watch are on the same network, and that the target port (xxxxx) on the watch is open and reachable from the PC.
Steps:
-
Check PC IP Address
- Open Command Prompt and run: ipconfig
- Note the IPv4 Address under the active adapter (Wi-Fi or Ethernet).
-
Check Watch IP Address
- Ensure the watch is connected to the same Wi-Fi network as the PC.
- On the PC, run: arp -a
- Identify the watch’s IP (e.g., xxx.xx.xx.x) from the list.
-
Ping the Watch
- Run: ping xxx.xx.xx.xx Replace with the watch’s IP.
- If replies are received, the device is reachable.
- If it times out, check the connection or Wi-Fi settings.
-
Test the Port Connection
- Ensure Telnet is enabled on the PC.
- Run: telnet xxx.xx.xx.x xxxxx Replace the IP and port accordingly.
- If the connection opens successfully → the port is open.
- If it shows “Could not open connection to the host” → the port is closed or inactive.
Notes
- If Wi-Fi debugging on the watch has been toggled off/on, the port number may have changed.
- Verify the current debugging port before running the tests.
- Ensure both the PC and watch are on the same Wi-Fi network.
- Confirm Telnet is enabled on the PC before testing.
Expected Outcome
After completing all steps, the user should share the outputs of:
- ipconfig
- arp -a
- ping
- telnet
This confirms whether the communication port (xxxxx) on the watch is open and accessible from the PC.
Applicable Scenarios
When preparing a watch for remote debugging or data communication over Wi-Fi, it is necessary to verify that the PC can reach the watch and that the specific debugging port is open.
