====== Basic Networking Commands ======

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

===== AT+WIFIMODE – Set the Working Mode =====

**Query:**  
  <code>AT+WIFIMODE=?</code>

**Set Mode:**  
  <code>AT+WIFIMODE=ap</code>

**Response:**  
  <code>OK</code>

**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:**  
  <code>AT+WIFIMODE=sta</code>

===== AT+SSID – Set the SSID =====

**Query:**  
  <code>AT+SSID=?</code>

**Set SSID:**  
  <code>AT+SSID=hgic_ah_test</code>

**Response:**  
  <code>+SSID:HALOW_959B60
OK</code>

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

===== AT+ENCRYPT – Set Encryption Mode =====

**Query:**  
  <code>AT+ENCRYPT=?</code>

**Set Encryption:**  
  <code>AT+ENCRYPT=0</code> (disable)  
  <code>AT+ENCRYPT=1</code> (enable)

**Response:**  
  <code>+ENCRYPT:0 or 1
OK</code>

===== AT+KEY – Set Encryption Password =====

**Query:**  
  <code>AT+KEY=?</code>

**Set Key:**  
  <code>AT+KEY=12345678</code>

**Response:**  
  <code>+KEY:12345678
OK</code>

**Notes:**  
  * Default key: 12345678  
  * Minimum 8 ASCII characters  

===== AT+PAIR – Pairing Control =====

**Set Pairing:**  
  <code>AT+PAIR=0</code> (stop)  
  <code>AT+PAIR=1</code> (start, default group)  
  <code>AT+PAIR=2</code> (start, group 2)

**Response:**  
  <code>OK</code>

**Notes:**  
  * AP must have SSID and key configured first  
  * Connection established automatically after pairing stops  

===== AT+CHAN_LIST – Set Channel List =====

**Query:**  
  <code>AT+CHAN_LIST=?</code>

**Set Channels:**  
  <code>AT+CHAN_LIST=9080,9240</code>

**Response:**  
  <code>+CHAN_LIST:9080,9160,9240
OK</code>

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

===== AT+BSS_BW – Set BSS Bandwidth =====

**Query:**  
  <code>AT+BSS_BW=?</code>

**Set Bandwidth:**  
  <code>AT+BSS_BW=4</code>

**Response:**  
  <code>+BSS_BW:4MHz
OK</code>

**Notes:**  
  * Supported values: 1, 2, 4, 8 (MHz)  

===== Notes =====

* 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.
