wifi

Is it possible to make the phone to "know" that a specific wifi network is at specific geographic location? if (answer == YES) { than how? } else { can the phone figure this out by himself? } Another similar question: is there any way to start monitor a region with accuracy of ~100m but telling the CLLocationManager to use only by wifi networks and cellular antenas? Because I don't want to power up the GPS no matter what... Thanks! iPhone positioning sucks and there is nothing you can do. If you jailbreak your device you can use the Apple80211 private framework to look up the available Wi-Fi

Blue led is blinking after powering up the module, the red one stays on, I can even connect to it via wifi. But I cannot program it. I tried Arduino IDE, different firmware flashers (Like NodeMCU, XTCOM). I'm using Arduino Mega. Here's my initial setup: VCC - 3.3 V on Arduino RST - nothing CH_PD - 3.3 V on Arduino TX - RX on Arduino (TX is transmitting data to RX, so I don't need a voltage divider, right?) RX - voltage divider (R1 = 10K, R2 = 20K) - TX on Arduino GPIO0 - GND on Arduino GPIO2 - nothing GND - GND on Arduino Then I tried uploading a sketch from the Arduino IDE and got the

I need to scan for available Wi-Fi signals and their strengths. I'm using wifiManager.startScan(); and asynchronous wifiManager.getScanResult(); . On devices without support of 5GHz band it takes about 500ms to get the results, on devices with 5GHz band support it takes about 2s, and that is too much for me. I guess the 1.5s delay is in searching the whole 5GHz band. Is there any way I could tell the device to scan only in the 2.4GHz band, or any other way I could get the results faster (for example through NDK)? I searched through the entire web and found nothing, so I guess this is the only

Is there a tutorial available which explains how to scan for available wifi networks via Objective-C in a mac app? I have been searching for the past few days but only found bonjour related results. I read that CoreWLAN framework is used for wifi scanning and communication, could anyone please guide me in this regards? I just want to create a program which scans for available wifi routers around. And then when I click on any of the router, it gives me a list of devices attached with that router. Is it possible? Best Regards Apple's Developer site has a nice sample project here which seems to

Based on recent empirical findings, and based on various posts on the web, it seems that an application running on an iPhone with personal hotspot enabled cannot send broadcasts and/or multicasts out onto the personal hotspot's network. Can anyone shed light on the cause of this problem? The Application I have an IOS application, built with cross-platform C++ code, that broadcasts and multicasts its presence onto the network it is running on. The application works flawlessly when the iPhone is connected to a Wi-Fi network. In this case, other devices on the network receive the broadcasts
