Basic Networking Commands

This page documents the core AT commands to configure HaLow firmware 2.x modules for basic network operation.

Query:

AT+WIFIMODE=?

Set Mode:

AT+WIFIMODE=ap

Response:

OK

Parameters:

• ap – Standard AP mode
• sta – Standard STA mode
• apsta – Relay mode (acts as AP and STA)
• wnbap – Private AP mode (V1.6 compatible, not default)
• wnbsta – Private STA mode (V1.6 compatible, not default)

Example:

AT+WIFIMODE=sta

Query:

AT+SSID=?

Set SSID:

AT+SSID=hgic_ah_test

Response:

+SSID:HALOW_959B60
OK

Notes:

• Default SSID: HALOW_xxxxxx (last 3 bytes of MAC)
• Max length: 32 characters (longer truncated)

Query:

AT+ENCRYPT=?

Set Encryption:

AT+ENCRYPT=0

(disable)

<code>AT+ENCRYPT=1</code> (enable)

Response:

+ENCRYPT:0 or 1
OK

Query:

AT+KEY=?

Set Key:

AT+KEY=12345678

Response:

+KEY:12345678
OK

Notes:

• Default key: 12345678
• Minimum 8 ASCII characters

Set Pairing:

AT+PAIR=0

(stop)

<code>AT+PAIR=1</code> (start, default group)  
<code>AT+PAIR=2</code> (start, group 2)

Response:

OK

Notes:

• AP must have SSID and key configured first
• Connection established automatically after pairing stops

Query:

AT+CHAN_LIST=?

Set Channels:

AT+CHAN_LIST=9080,9240

Response:

+CHAN_LIST:9080,9160,9240
OK

Notes:

• Frequency = center frequency × 10 (9080 → 908 MHz)
• Up to 16 points, comma-separated

Query:

AT+BSS_BW=?

Set Bandwidth:

AT+BSS_BW=4

Response:

+BSS_BW:4MHz
OK

Notes:

• Supported values: 1, 2, 4, 8 (MHz)

* Configure SSID, encryption, key, mode, channels, and bandwidth before connecting STAs or relays. * Use `AT+WIFIMODE=ap` on AP side and `AT+WIFIMODE=sta` on clients.
