Software & SDK

SDK: https://github.com/WRTnode/openwrt Software:

  • Based on OpenWrt CC 1505
  • Differences for OpenWrt:
    • Defalut network segment of IPv4: 192.168.8.1
    • Adding wwan as port apcli0, and WRTnode wireless management tools: aps/setwifi/vw/ia
    • Adding MTK WiFi driver: ralink-wifi/ralink-ralink-mt76x8, which have been adapted to OpenWrt CC
    • Adding WRTnode Package feeds
    • Adding SPI-CS1 driver

Wireless networking performance and CPU benchmark

Wireless networking performance

WiFi to RJ45 (LAN) throughput 175.307Mpbs (tested by IxChariot, do did below)

WiFi via nat conversion to RJ45 (WAN) throughput 180.526Mbps
2P-introduction12.png

WiFi(LAN) to WiFi(LAN) dual wireless throughput 85.412 Mbps

  • All the test performed in a relatively ideal environment, instead of in the shielding box. WRTnode2P uses the 5DBM FPC external antenna as the retail one:

Encoding the same wav file copy by the 5 devices using the fixed-encoder

Power consuming

Power on, WiFi off: around 3.3v*140mA
Power on, WiFi on, ordinary WiFi throughput: around 3.3v*200mA
Power on, WiFi on, max WiFi throughput: around 3.3v*300mA
