I'm trying to implement a network by using the EZ430RF Polling_With_AP Application of Simpliciti.I want it to be an ED-AP-RE-ED.
The goal of the Range Extender is, of course, to extend the range of the network. Unfortunately, it doesn't work :
I made "range tests" in a building with a "Sender-AP-Receiver". The maximum range between the Access Point and an ED was about 40m, after that, it doesn't receive any frames.
Then, I tried with "Sender-AP-Range Extender- Receiver", but the new range of the network is...the same (there was 20m between the AP and the RE). Why doesn't it work?
I made the tests this way : I turned on all the devices (which are on batteries) and i moved away with one ED until the sniffer doesn't find anything.
The sniffer indicates that the RE works properly (it repeates the frames well), but the range is not extended.
Do you have an idea to fix it?
if it is repeated then the ED should receive the message if it is in range of the RE. What values did you define by MAX_HOPS and MAX_HOPS_FROM_AP in smpl_nwk_config.dat? If you copied the values of the simpliciTI example then this would explain your error. The settings are for an ED-AP-ED configuration.
Set MAX_HOPS_FROM_AP to 2 then it should work.
I tried to modify the MAX_HOP and the MAX_HOPS_FROM_AP, but it didn't change the range :(
What values did you try?
MAX_HOP=3 and MAX_HOP_FROM_AP=2
Did you see the repeated packets of the RE outside of the AP range with the sniffer?
Try to power up the ED from a distance outside your original range. That way it should talk to the Repeater first, even for linking. Maybe you need to establish the link through the repeater and can't move the unit after a link is established.

Thanks, I tried your way and it works fine!!!
