8 Wifi
The RINGNECK SOM-PX30-uQ7 module features an on-board Wifi module. This chapter shows how to connect
to an existing Wifi network and how to flash the wifi firmware, should the need arise.
8.1 Antenna
The development kit includes an antenna compatible with the Wifi module. Other antennas can be used. The
connector on the antenna must be one of:
• W.FL Series connector from Hirose
• MHF III connector from I-PEX
• AMMC connector from Amphenol
8.2 Connecting to a Wifi network
You can show the available wifi networks using:
nmcli dev wifi
Connect to a network using the following command (replace the network name and password as appropriate):
nmcli dev wifi connect
You should get a message like:
Device
'wlan0'
successfully activated
You should have connectivity over Wifi now. You can check the IP address you received using:
ip addr show dev wlan0
Note: By default, nmcli is not available in our Yocto core-image-minimal image. However, it is available in our
Yocto theobroma-extended-image image.
8.3 Flashing the wifi firmware
You need to have esptool.py installed on the module.
The wifi firmware consists of three files:
• bootloader.bin
• partition-table.bin
• eagle.bin
Save all three to the /tmp directory on the module.
Then flash the wifi module as shown below:
v1.3.1
