Is it possible to operate the Toradex Wi-Fi without an antenna?

The question is in the title. nmcli device wifi list
returns no devices.

Greetings @einoj,

It is always recommended to use the onboard WIFI chips on our modules, with an antenna attached. While it is technically possible for the chip to detect a WIFI device with no antenna the range and signal strength would be so low it would be impractical to work with.

Please let me know if these issues persist even with an antenna attached.

Best Regards,

Thank you Jeremias. I ordered two antennas (H2B1PD1A1C385L). With them connected the WIFI works with no issues.
