Network / TCP/IP Commands

This page documents AT commands for network testing, TCP/IP flow, and connectivity functions in HaLow firmware 2.x modules.

Execute:

AT+IPERF2=c,192.168.123.2,5002,60

*(client send)*

<code>AT+IPERF2=s,5002</code>  *(server receive)*

Parameters:

• `c/s` – “c” = client, “s” = server
• `ip_addr` – target IP address
• `port` – TCP port number
• `time` – duration in seconds
• Requires `SYS_NETWORK_SUPPORT` macro to be enabled

Execute:

AT+PING=192.168.123.2,5,1024

Parameters:

• `ip_domain` – IP address or domain name
• `send_times` – number of packets
• `size` – packet size in bytes
• Cannot enter other AT commands while pinging
• Requires `SYS_NETWORK_SUPPORT` and `LWIP_RAW` macro definitions

* `AT+IPERF2` helps measure TCP throughput between two modules. * `AT+PING` can be used to check connectivity and latency. * Ensure that network support macros are enabled in firmware for these commands to work.
