AT Command Usage Examples

This page provides example sequences for using HaLow firmware 2.x AT commands in typical module configurations, including basic connection setup, relay configuration, and STA setup.

1. Basic Module Connection Setup

When initializing a module, set frequency, bandwidth, SSID, and password: 

AT+CHAN_LIST=9080,9160,9240   # Set 3 channels
AT+BSS_BW=8                   # Set 8 MHz bandwidth
AT+SSID=hgic_ah_test          # Set SSID
AT+ENCRYPT=1                  # Enable encryption
AT+KEY=12345678               # Set encryption key
AT+WIFIMODE=ap                # Set AP mode (or STA mode)

2. Configuring a Relay Network

AP Modules

1. Configure AP SSID: 

AT+SSID=ssid1

2. Disable encryption (optional for easier configuration): 

AT+ENCRYPT=0

Relay Module

1. Set role to relay (AP+STA mode): 

AT+WIFIMODE=apsta

2. Disable encryption: 

AT+ENCRYPT=0

3. Configure relay downstream SSID: 

AT+R_SSID=ssid1_r1

4. Configure relay SSID to connect to upstream AP: 

AT+SSID=ssid1

STA Modules

1. Set STA SSID to match relay’s downstream SSID: 

AT+SSID=ssid1_r1

2. Disable encryption (optional): 

AT+ENCRYPT=0

Notes

* Always configure basic network parameters before enabling relay or roaming. * Encryption can be enabled for secure networks; disable only for test or simplified setups. * Use the examples above as a starting point for building multi-hop HaLow networks.
