===== MQTT Settings in RADIUSdesk =====
  * To enable MQTT on RADIUSdesk there are two places where it has to be configured.
  * For the devices managed by MESHdesk and APdesk there is this GUI under **Settings** -> **MQTT**

{{:getting_started:mqtt_settings.png|}}
  * Command topic is always **/RD/NODE/COMMAND/RESPONSE**
  * Then for the server to use MQTT instead of the heartbeat system you have to edit the following config file.
  * Edit **/var/www/html/cake4/rd_cake/config/MESHdesk.php**
  * Look for this sections and adapt to your server's values.
<code php>
$config['mqtt_settings']['enable_realtime']	= true;
$config['mqtt_settings']['api_gateway_url']	= 'http://164.160.89.129:8001';
