====== Roaming Commands ======

This page documents AT commands for configuring roaming behavior in HaLow firmware 2.x modules.

===== AT+ROAM – Enable or Disable Roaming =====

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

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

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

**Notes:**  
  * Roaming must be enabled only on STA devices  
  * Supports SSID matching modes:  
    * Full word match – all APs have the same SSID (≤32 characters)  
    * Fuzzy match – last three characters differ; SSID > 8 characters total, with common prefix + 3-character ID  
  * Roaming parameters are saved across power cycles  

===== Notes =====

* Roaming allows STA devices to automatically switch between APs in a multi-AP network.  
* Ensure SSID and security keys are compatible across APs for smooth handoff.  
* Combine with relay configuration for extended network coverage and mobility.
