For using Sample Firmware Version (ESP-IDF v5.4-dev-624-g3d167a46ff-dirty):
Recommended Usage Steps:

1. Connecting to a 2.4G AP:

• 1.1. Switch band to 2.4G: band 1

• 1.2. Scan for 2.4G AP: scan

• 1.3. Connect to the AP: sta

• 1.4. Perform an iperf test:
  iperf -s (as TCP server)
  iperf -s -u (as UDP server)
  iperf -c xxx:xxx:xxx:xxx (as TCP client)
  iperf -c xxx:xxx:xxx:xxx -u (as UDP client)

2. Connecting to a 5G AP:

• 2.1. Switch band to 5G: band 2

• 2.2. Scan for 5G AP (5G channels are more than 2G and include DFS channels, so the scan time is longer than for 2G): scan

• 2.3. Connect to the AP: sta

• 2.4. Perform an iperf test (If no data is sent or received within 10 seconds, iperf will be aborted, and the socket will be closed and shut down.):

  iperf -s (as TCP server)
  iperf -s -u (as UDP server)
  iperf -c xxx:xxx:xxx:xxx (as TCP client)
  iperf -c xxx:xxx:xxx:xxx -u (as UDP client)
  

Know issues:

1. The serial port baud rate is 138240; using 115200 will result in garbled output.

2. After the device starts, it defaults to the 5G band, contrary to what is described in the log as 2G. You can switch between the 2G and 5G bands using the band command: band 1 switches to 2G, and band 2 switches to 5G.

3. On the 5G band, Wi-Fi scanning cannot detect APs on channel 36, and connections to these APs cannot be established. For this firmware version, it is not recommended to use the device in softAP mode.

4. When the softAP is operating on the 5G band, it defaults to channel 36 instead of channel 112, as described in the log.

These issues have been resolved in commit 34813ec. If you encounter the above issues, sorry for not providing a timely update on the aforementioned issues.And please update to this version and use the iperf example for testing. (Note that in the new version, some commands differ from those in the sample firmware, so please be aware when using them.)
And also, thanks to @ESP32DE for reporting these issues.

I have a question regarding the C5 Wifi band switching. Does it automatically connect to the 5G or 2.4G of the AP (the AP has dual band enable on the same SSID) and switch to best band when available especially when roaming ?. Thank you.

[xuxiao111]

Hi @alberk8 , when the AP uses the same SSID and password for both 2.4G and 5G, the STA (station) will automatically choose the best band to connect to. Considering that the 5G signal attenuates more than 2.4G at the same distance, we have added a configuration option, rssi_5g_adjustment, to help decide whether to connect to the 5G or 2.4G band.
