What's in the WRTnode2R retail package
How WRTnode2R inserted into the shield
Plug the golden core module WRTnode2R into the miniPCI socket as the angle like the figure:
And push the outside of the golden module lightly, as the figure:
After a "carrrrrh" sound, the core module and the base board fitted each other perfectly, as the figure:
Isn't the inserting of WRTnode2R looks like the inserting of the RAM stick to the laptop? Yep, it's just how we want to design.
Light up WRTnode2R
- The board is powered by micro-USB connector, find an ordinary micro-USB power cable( which is not included in the retail package)
- Plug into the baseboard's micro-USB connector, and the other side you could use any USB port which could offer more than 500mA and 5V power, such as a computer or a laptop's USB interface or a mobile phone charger or something like this.
- The blue LED lights on and the OpenWrt starts to run in the board.
- 20 seconds later, you will find a Wi-Fi with the SSID like WRTnode2R_xxxx( xxxx means the last four byte of the MAC address of your WRTnode2R), you could connecting the Wi-Fi with computer or phone with the password 12345678.
Login to WRTnode2R using telnet or ssh
Use any PC with Windows, Linux or MacOS operating system, install PuTTY on Windows PC, use any Linux / MacOS terminal software on Linux / MacOS.
- First ping the WRTnode to see if connection is available. The default IP of WRTnode2R is set to 192.168.8.1, but WRTnode2R is able to resolve openwrt.lan to 192.168.8.1 as well:
- Connect to WRTnode2R using telnet or ssh
If you connect first time to WRTnode2R or you didn't set password for root user of OpenWrt, use telnet to connect:
If you a password for root user was set, use SSH to connect:
No internet no happiness
Now we will connect WRTnode2R to the internet. of course, you must have a 2.4G Wi-Fi ap or router with has connected on the internet.
'aps' is the command of WRTnode2R to scan the Wi-Fi available, the output of 'aps' looks like this:
WRTnode AP scaner. Begin scaning APs, pls wait... Finished. APs available are... ra0 get_site_survey: Ch SSID BSSID Security Siganl(%)W-Mode ExtCH NT WPS DPID 1 Tenda xx:xx:xx:xx:xx:xx NONE 70 11b/g/n ABOVE In YES 1 hshn xx:xx:xx:xx:xx:xx WPA2PSK/AES 96 11b/g/n NONE In YES 6 TP-LINK xx:xx:xx:xx:xx:xx NONE 55 11b/g NONE In NO 6 BY01 xx:xx:xx:xx:xx:xx NONE 100 11b/g/n NONE In YES 6 Tenda_xxxxxx xx:xx:xx:xx:xx:xx WPAPSK/AES 50 11b/g/n ABOVE In NO 11 CU_wpFS xx:xx:xx:xx:xx:xx WPAPSK/TKIPAES 70 11b/g/n NONE In YES
ok，we will connect one:
root@OpenWrt:~# setwifi SSID_you_connetctin the_password
be careful, there's a space between the SSID and the password
root@OpenWrt:~# setwifi TP_linkAB33CD my_password
Press Enter and wait 5 seconds, or sometimes we need to reconnect our computer to the WRTnode2R's SSID, so let's see if we have got the IP address from uppter router:
root@OpenWrt:~# ia apcli0 Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx inet addr:192.168.1.103 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: xxxx::xxxx:xxxx:xxxx:xxxx/xx Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
sometimes getting the IP address will lasts more than 5 seconds, so be patient. Once we got the IP address, let's see if the board have access the internet:
root@OpenWrt:~# ping baidu.com PING baidu.com (184.108.40.206): 56 data bytes 64 bytes from 220.127.116.11: seq=0 ttl=54 time=6.071 ms
See, thus we connected our computer to the WRTnode2R, and we connected the WRTnode2R to the internet.

Updating the firmware of stm32
In the stm32 of WRTnode2R/en, we preset a bootloader in the first 4K of stm32 so we could update firmware of stm32 online in mt7688, which provide by a 7688 tools named flash-stm32.
Using flash-stm32 like:
root@OpenWrt:~# flash-stm32 URL
URL argument could be the file url from internet or the local file.
We recommended to update the new firmware：
root@OpenWrt:~# flash-stm32 http://d.wrtnode.com/2R-stm32/WRTnode2r_stm32_V1.bin
As shown, stm32 updating finished, after that stm32 will reboot automatically.
If user want to do stm32 development by yourself, use tools like stlink to deleop/debug/reflash. Here's what we must know:
- User-developed code to redirect to the interrupt vector table location 0x08001000.
- User Codes, the position to be downloaded to 0x08001000.
- If the user completely abandoned the code we provide, but also want to support online update firmware, you need to realize 7688 control stm32 reset function in the user code.(In we provide in the code, has achieved the reset command, so based on the code we provide for development, do not need to complete this step)
Try msh on WRTnode
STM32 running on the real time operating system RT-Thread,Benefit from the RTT in a friendly msh command line debugging components, our factory firmware implemented the RTT spi slave device driver, and the msh input and output ports are mapped to the spi bus.At the same time,We provide the software by 7688 and STM32 SPI bus communication(Including spiS0 device driver, spi-bridge communication software and flash-stm32 firmware upgrade program)
msh command line
- Login to WRTnode2R.
- Use the spi-bridge command to open msh terminal,then press the 'tab' key and the 'enter' key to list all available commands.
- For example, run the ps command.
- Use the 'exit' commad exit msh terminal.
More about WRTnode2R stm32 introduction, please refer to the manual of STM32 development in WRTnode2R
Restore To Factory Settings
Then you could do whatever you want in WRTnode2R via ssh, just like an ordinary Linux PC, and when you done something you dislike and want to restore the board as you first getting it, here's how:
root@OpenWrt:~# firstboot This will erase all settings and remove any installed packages. Are you sure? [N/y] y /dev/mtdblock5 is mounted as /overlay, only erasing files root@OpenWrt:~# reboot
This SDK is an universal one for all WRTnode hardwares, and for WRTnode2R choosing [ WRTnode 2 series ] in [ Subtarget ] when make menuconfig.
