问题 i use customer message and send it broadcast over radio channel, i use example 6 ( CounterSend ) from this link . when i build this project as micAz on mote 1, after this i use Xsniffer (TOSBase) on the mote that i will use it on the serial usb board (520). after that i open Xsniffer program to see the radio packet and they appeared as following : on other hand, to use Xserver i use XMeshBase then type on cygwin terminal : xserve -device=com4 i got this!! but i can't understand what it

问题 I am trying to write a script in Python 3 but all modules available today work on python 2 which will enable me to search for wireless networks and to connect to them. Is there any Python 3 library for this? The code I tried for python 2 from wireless import Wireless wireless = Wireless() wireless.connect(ssid='ssid', password='password') which is giving me an error Traceback (most recent call last): File "<stdin>", line 1, in <module> File "C:\Users\Himanshu Poddar\AppData\Local\Programs

问题 The Goal: Drive several servo/RC motors wireless from one pi to another pi. In essence, I want to build a RC remote control using a pi, with a second pion the receiver end. Now I have a serial transmission over a RF link module that is stable and has very few corrupt entries. The serial transmission has a max baud rate of 4800 due to the RF link module. Problem: It seems there is a 2-4 seconds difference between the transmitter pi printing values and the receiver pi printing values. I cannot

问题 I'm trying to get the SSID of my wireless network device in Java. I tried the official network tutorials http://java.sun.com/docs/books/tutorial/networking/nifs/retrieving.html but getDisplayName() getName() don't return SSID. Is there a way to get an exact SSID? Also, I'm also trying to read the wifi signal strength of all my network devices and couldn't find a way to do it. Can anyone please direct me from where to get all these information (tutorials, code samples etc)? Thanks 回答1: This

问题 I am currently building an AIR app for iOS, targeting iPad, with Flash CS5.5. I realize Flash gives me the option to build and deploy the app as an ad-hoc deployment which is fine. But what I'd really like to do is replicate the process here: How to distribute ios application wirelessly without managing UDIDs and recompilation Where I can point users to a web link that lets them install the app on their device, regardless of whether their UDID is in the provision. Flash generates the ipa file

问题 I've got a set top box running linux kernel 2.6.32 (cannot upgrade, please don't suggest that). I'm using the Realtek 8192CU driver configured to use the WEXT driver. What would cause iwlist scan to constantly return cached results? It seems when the STB boots and does its first scan, it gets an accurate list and connects to an access point just fine. However, subsequent scans return the exact same info (even signal strengths and qualities are identical). Rarely, a scan will return new

问题 Use Case: We have an iOS application where you can run a network test between an iOS device and its associated wireless access point to test throughput. The app can get the IP address of the iOS device just fine, but the user has to type in the IP of the access point. Problem: The task is to get the IP address of the associated access point, and pre fill it for the user, hence avoiding user intervention there. My Approach: Find out the Mac Address/BSSID of the access point. I do this by

问题 I would like to connect to my wifi network using python. I know the SSID and the key for the network, and it's encrypted in WPA2 security. I have seen some libraries like wireless and pywifi but the first didn't work and the second was too complicated. What is the simpelest way to connect to wifi? what is the best library/way? My failed code using wireless library (I've installed it via pip, of course): from wireless import Wireless wire = Wireless() wire.connect(ssid='myhome',password=

问题 My goal is to have remote control of a device on a WLAN. This device has software that enables me to configure this wireless network (IP, mask, gateway, dns). I can successfully connect this device, and my computer to a common network. Since both machines share the same network, I made the assumption that I would be able to open up a socket between them. Knowing the IP and port of the device that I am attempting to control remotely I used the following code, only to receive a timeout: import

问题 Is it possible to deploy an app on a friend's ipad for testing without the app being on the app store yet. My friend is far away so cannot connect to my mac via usb. 回答1: If the UDID of your friends iPad is added to your developer account and you compiled the app with an Ad-Hoc distribution profile, you can just use the Product -> Export Menu Item in Xcode and email him the .ipa File. He can use iTunes to drop the file onto his iPad. Another good solution to distribute beta versions of your
