Network / TCP/IP Commands
This page documents AT commands for network testing, TCP/IP flow, and connectivity functions in HaLow firmware 2.x modules.
AT+IPERF2 – TCP Flow Test
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
AT+PING – Ping Function
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
Notes
* `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.
