Prerequisites

Before you begin, see Qualcomm Linux Build Guide for common infrastructure setup and build workflows. This information describes the prerequisites to bring up WLAN functionality, such as setting up a Secure Socket Shell (SSH) connection and verifying and storing the Media Access Control (MAC) address. The following workflow shows how to get started with the Wi-Fi bring up procedure followed by configuring Wi-Fi according to your requirements.

​
Set up UART/SSH

To set up debug Universal Asynchronous Receiver/Transmitter (UART) and Wi-Fi, and to connect to SSH, see Sign in using SSH. Note When using the Secure Copy Protocol (SCP) to transfer files to or from a device, a password prompt appears. Enter oelinux123 in the password field.

​
Set WLAN MAC address

Note:
This is an optional step. If you want to have your own MAC address and not the default MAC address, perform the following steps:
  • By default, the factory writes the WLAN MAC address in the one-time programmable (OTP) memory of the network card. You can modify the MAC address using the following commands, if required. In these commands, replace wlpXsY with the interface index name 0 or 1. For example, wlp1s0 or wlp1s1. 
    ip link set wlpXsY down
ip link set wlpXsY address xx:xx:xx:xx:xx:xx
ip link set wlpXsY up
  • The MAC address that you set persists until a restart or the next power cycle and takes precedence over the factory-set MAC address stored in OTP memory.
Note:
As Predictable Network Interface Names enabled by default:
  • For non-PCIe interfaces, the WLAN interface name is wlanX (RB3GEN2, Shikra).
  • For PCIe interfaces, wlanX is renamed to wlpXsY, where:
    • X = PCIe port index + 1
    • Y = device index
