How to do settings to allow access 6lbr from Internet

The following steps show you how to do settings to allow access 6lbr from Internet. Let's say we have a Internet router (mine is Asus RT-N12HP_B1) and the LAN address is 192.168.1.xxx.

1. Access to 6lbr web page (http://[bbbb::100]) inside LAN and go to configuration page of 6lbr. Select IP64: on, DHCP: off, input a IPv4 address 192.168.1.2 (this might be different if you don't use 192.168.1.xxx as LAN address on your Internet router and you can use other IP such as 192.168.1.123 if you like it more.), and set Gateway as 192.168.1.1 (this might be also different if you don't use 192.168.1.xxx as LAN address on your Internet router). Then, press "Submit" to restart 6lbr.



2.  After restarting, you can check IP64 Address is 192.168.1.2 now on 6lbr Info page.


3. Next, let's check settings on Internet router (mine is Asus RT-N12HP_B1). We can see the external IP of this router is 220.136.172.175.



4.I add a port forwarding rule (assign http service port to 6lbr IPv4 address 192.168.1.2) to this Internet router and restart it.



5. Now, I can access 6lbr from another desktop from elsewhere on Internet by http://220.136.172.175



Conversion between RSSI and LQI in Z-Stack

Z-Stack uses the following formula to convert RSSI and LQI.

LinkQuality = [255* (RSSI-MIN_ED)]/[MAX_ED-MIN_ED]

Therefore with simple algebra

RSSI = MIN_ED+LinkQuality*( MAX_ED-MIN_ED)/255

Default values for MIN_ED and MAX_ED are -87 and 10 respectively.

Then, maybe you can convert RSSI to distance...

Use ZTool + Z-Stack 3.0 ZNP to set up a basic Zigbee 3.0 network

The following steps show you how to use ZTool + Z-Stack 3.0 ZNP to set up Zigbee 3.0 network:

1. You have to prepare two CC253x EVBs (CC2530DK, CC2531EMK, or CC2538EM) and run Z-Stack ZNP 3.0 FW on it.

2. You can run the following MT commands (TX in red) to setup Zigbee 3.0 coordinator.

Build cc26xx-web-demo for CC2650 LaunchPad by "make TARGET=srf06-cc26xx BOARD=launchpad/cc2650 cc26xx-web-demo.bin" and download cc26xx-web-demo.bin to your CC2650 LaunchPad. Let it join 6lbr and you should see resource adc/dio23 on COAP interface. You can press Get button to get the ADC reading from DIO23. Try to connect different voltage (0-3.6V) to test.
