Just for reference the Sony Remote Camera API only works by using a 1:1 Wifi Connection
The Wifi signal strength of my Sony DSC-HX60V camera already drops after a few meters distance. But I want to be able to remotely control the camera over a range of 50 meter. There is no way that the onboard Wifi can achieve this range.
So now Iam looking for a solution to this problem. If it helps a local Wifi router exists that covers the whole range:
A normal Wifi repeater seems to be the best option, but according to a Forum Post using a repeater does not work, because the repeater acts a client and the camera can only connect to one client at the same time. Did someone got it to work with a repeater?
Additionaly I was thinking about using a Raspberry Pi with a second Wifi adapter that connect to the local Wifi and manages the API requests.
Any other ideas?
Disclaimer:
Even tho this Question may be more Hardware and Network related and thereby fits more into the SuperUser Network. A working Network connection does not necessary imply that the API is working aswell. This is why I posted this Question here
If you have a router which can work in 'client mode' that should be able to make a 1:1 connection with the camera, and then present that link over ethernet - you may have issues with network addresses and/or discovery if your main network is a different IP range to what the camera offers/DHCP's.
Some of the Sony cameras support 'multi-wifi' where the camera connects to an external device (normally the LiveViewRemote, but can be a router). Unfortunately the HX60 (and presumably any of the Play Memories SmartRemote app based ones) does not seem capable of this.... maybe the QX1 is an exception as it's supposed to work like this.
This connection connection is managed via WPS, and once connected the RemoteAPI works well. Works for my AS100.
If you are looking to set up a RaspPi, I can confirm that it works with this Python library:

I want to send data(I think I can achieve it sending http requests) between two ESP's that are connected to the same LAN. I don't want to use one as an access point! I have one esp that is acting as a homekit device, and I want to send data(for example, sensor readings) to it from another esp. I've seen many tutorials where one device is acting as an access point, but that's not what I need. I also don't really need to access the esp data directly from my laptop, so I believe I don't need the html page. I would appreciate any help, code, or any existing tutorials, because I didn't find a single one.
Configuring one ESP as an AP is only done for convenience. You can configure both of them in STA (station) mode and they will connect to, e.g. your phone hotspot or your wifi router.
Connected to the same hotspot, they are on the same network, and they will be able to communicate with each other (unless the hotspot is configured to not allow this ... ). The tricky part will most likely be for the "client" to determine the IP address of the "server" in order to create the connection.
If you have admin access to the hotspot, you can cheat and hard code the IP addresses (assuming that the hotspot will assign the same IP address to the device the next time it sees it.)
It's also not difficult to use mdns (aka bonjour), which allows a network device to assign itself a local hostname. So you can name one ESP ("myserver") which allows the ESP running the client code to connect to "http://myserver.local"
I would like to understand it is possible to switch the ESP8266 connection between the cloud and WiFi LAN.
There are two paths to control the sonoff switch, connected to a wifi router. In case the phone is connected to the router, Path 1 acts as LAN network and ESP8266 can be controlled even without internet. In case I am not at home and would like to control the switch remotely via cloud, path 2 would be followed. Thus, I could get the best of both worlds.
From all the examples that i have seen so far ESP8266 could be operated in only one mode at one point of time, either Lan or cloud (both via the WiFi router).
So kindly help me with the switching code/logic, that will wait to work upon the commands provided via LAN mode if there are none left. Now it should work upon the instructions after switching to cloud mode and finally return to LAN mode after sometime and so on.
For security reasons your Sonoff device should not be reachable from the internet directly - ever. It should only be accessible within your local (home) network. That's your path 1.
To enable path 2 - without affecting the Sonoff device at all - you need a way to build a VPN from your smartphone to your local network. For the node it will look like all traffic is coming from your local network even though you are actually connecting into it from remote.
A fairly simple and cost-effective way to achieve this is to run PiVPN on a Raspberry Pi. See e.g. this video for instructions: https://www.youtube.com/watch?v=15VjDVCISj0
I have a raspberry pi (model 3 B+) acting as a wireless access point. I would like the pi to be able to connect to an available wifi network while remaining a wireless access point.
The use case for this would be as follows:
Connect to the access point from a laptop
From the laptop, navigate to pi_ip_address:port in a browser
From the browser, a list of available networks would be shown
From the browser, select an option and enter the password
From the Pi, connect to the selected network
Is this possible? If so, has anyone had success doing this and/or is there documentation available?
Thanks in advance
we are doing a project on image processing using a camera,raspberry pi3 and a gsm module. Above mentioned things are with a flying drone. I can send a notification message to a mobile using gsm module if required object detected on the cam. But we store that image to view on a webpage or through a mobile app easily. while it's flying it can't connect to the internet. So can you suggest a solution to get those images when it is inside our home wifi range.(any how we can get the images from sd card but i need to get those as soon as possible it detected the wifi) . Thanks in advance
You could consider using "tethering", a.k.a. "Personal Hotspot" in Apple parlance, on your mobile phone.
Basically, you would enable the Personal Hotspot on your iPhone and allow your RPi to connect to it via Wifi. You would have to check your setup, but my iPhone takes IP address 172.20.10.1 for itself and dishes out IP addresses to clients which are the same but with the 1 replaced by a small number under 13.
You can see from here how to setup your RPi to automagically connect to your Hotspot whenever in range. You could also consider fixing a static IP address when on that network, so you know where the RPi will show up for sure.
You would then ensure that Apache, or maybe lighttpd which is lighter weight, is running on your RPi.
Then, your app on the RPi would store its image as image.jpg in Apache's DOCUMENT_ROOT directory, probably /var/www/html/image.jpg but check.
Now, on the iPhone, start Safari and browse to:
http://172.20.10.N/image.jpg
where N is a small number. You should see your image and be able to save it to DropBox or Photos or iCloud Drive for others to see.
Of course, once your RPi is connected to your iPhone's hotspot, it can FTP or ssh copy the image to any website or other server on the Internet it has access to itself.
I have understood your question also I have cheapest solution to build your project. you will be needing 3 modules
ESP8266 (Wifi module)
SD card logger
Camera module(go with your choice, try ESP8266(But I have not tried it))
Combining all these can get your work done. But most instructing part is When connected with wifi it should transmit video to webpage or app and when not connected should log video to SD card
Below is my try to solve your problem, if you have any doubts feel free to ask your question.
ESP8266 is an WiFi module, you can connect it with an hot-spot or an router, similar to any WiFi device's on successful connection it throws 200,OK failing will throw 404 or so. Technically just like any TCP devices it will work. You can connect, disconnect, send and receive data continuously using software(using code you write).
0-code for camera unit starts
1-try connecting WiFi && start the camera and start logging into SD card //InCase if WiFi module takes longer time than usual to connect, this will prevent data from losing
2-if connection failed - continue writing to SD card
3-else(connection made) - start streaming the data && stop the SD card logging and save the file and create a new empty file so that we can save on next connection out without wasting data.
4-check for connection status in regular interval (goto step2).
5-on any external inputs(like click an image)
most important thing: code for your camera interface should work independent from the flight controller code.

I want to try to set up an ESP8266 (using the Arduino IDE) to occasionally connect to a wifi SSID to send telemetry back. I also would really like to be able to have it running a softAP for configuration/settings purposes. (i.e. so if you want to change internal settings in your code, you can connect directly to the device to access a web form to do so)
The problem is, I am not 100% sure how I know which is which when making an outgoing telemetry json query. I want it to go out on the STATION mode connection. Presumably in most cases the AP mode won't be connected, but there may be rare instances where both are connected at the same time. Thus how do I tell the device to specifically use the STA side of things when it needs to send data back over the internet?
I can't even seem to find any specific examples to ask if one or the other is connected. (you can poll WiFi.status() but - which one is it reporting?)
Any help is appreciated
