5.3. WiFi band settings USR-DR164 supports 2.4G & 5.8G dual band WiFi, users can set it using AT+WFREQ command. In 2.4G & 5.8G dual-band, when connecting as a STA to a router with the same SSID, USR-DR164 connects to the router with better signal strength with priority. -
Page 20: Heartbeat Packet
USR-DR164/162 User Manual 5.4. Heartbeat Packet In the network transparent transmission mode, the user can choose to enable the custom heartbeat packet function. The heartbeat packet can be sent to the network or serial device: The main purpose of sending to the network is to maintain a connection with the server, and at the same time let the server that is idle for a long time (do not send data to the server for a long time) to detect whether the current connection status is valid. - Page 21 USR-DR164/162 User Manual be sent to the network. AT+HEARTTP=NET (3)Set the heartbeat packet data (maximum 40 bytes). For example, to set the data to the string www.usr.cn, you need to first convert the string to hex 7777772E7573722E636E. AT+HEARTDT=7777772E7573722E636E (4)Set the interval for sending heartbeat packets. The setting range is 1-65535s, and the default is 30s. For example, set the sending interval to 30 seconds.
