At+Qiswtmd Switch Data Access Mode; At+Qping Ping A Remote Server - Quectel BG96 TCP/IP Application Note

2.2.10. AT+QISWTMD Switch Data Access Mode

The Write Command switches data access mode between buffer access mode, direct push mode and
transparent access mode. When starting a socket service, the data access mode can be specified by
<access_mode> of AT+QIOPEN. After the socket is opened, the data access mode can be changed via
AT+QISWTMD.

2.2.11. AT+QPING Ping a Remote Server

The Write Command tests the Internet protocol reachability of a host. Before using ping tools, the host
should activate the context corresponding to <contextID> via AT+QIACT first. It will return the result
within <timeout> and the default value of <timeout> is 4.
