12/24/2023 0 Comments How to scan wifi channels in useThis behavior is very similar to the process of setting up Google Chromecast.Ĭhromecast also has two wireless interfaces and change the channel, but the Phone does not lose connection with it. Is there a way to tell the Phone (or other device) about network change? Or perhaps increase the likelihood that the phone is connected back to DeviceAP. Therefore Phone lost DeviceAp and starts roaming. The channel of wlan1 also changes (maybe in hard way). Because WiFi module can work only on one channel. When wlan0 starts connecting to RouterAp it changes working channel. Then the phone sends a request to the device to connect to RouterAp. Device interface wlan0 is not configured and not running. We have a Router with essid RouterAp which is on channel 6. Let's assume that the phone already connected to Device wlan1 interface with essid DeviceAp which is on channel 1. Here is more clearly description what is going on on device. Is there a way to change wi-fi channel but keep connection between the device and mobile phone? When channel changes phone looses connection with the device. The program will load and then detect the connected printer in your network. This is a simple way to find devices nearby, track sig strength, MAC addresses and what channel they are using. Look for the HP Deskjet 5520 series program or HP Scan link. This is a simple way to find devices nearby, track sig strength, MAC addresses and what channel they are using. ![]() This causes channel of wlan1 to change in order to match of channel for wlan0. From your computer desktop, click on Start menu then Programs. ![]() Both interfaces (wlan0 and wlan1) must work on the same channel as we have single hardware module. Device in turn connects to another wi-fi network using wlan0 and notifies the phone if connection was successful or not.īut there is one issue. Phone connects to the device via wlan1 and sends command for the device to connect to another network and waits for result. One of the interfaces works in Master mode. It is controlled via mobile app.įor configuration purposes we use wi-fi module that can work in both STA + AP modes simultaneously via two interfaces wlan0 and wlan1. We are developing small internet connected device that connects via wifi and does some work.
