Question: Can you set an AirPlay passcode in order to connect?
Document: So the device emits a wifi network signal. You connect your iPhone to that network and you can use Apple's AirPlay to transmit audio. Great! The only problem for me is that all my audio is streamed from the net. Which I just had to disconnect from in order to connect to the wifi provided by the speaker. So the receiver works perfectly but I've lost everything that I wanted to listen to.
SABRENT has created a small, lightweight receiver that transforms any powered speaker or stereo receiver into an AirPlay-enabled system. It is a WiFi receiver so any of your devices set to use WiFi can use this. The instructions on the video included on the Amazon page are clear and easy to follow. It is not simply a plug and play device, but with a bit of patience putting it into use is relatively simple.
I was going to give it a 1 star rating due to the difficulty to use it with an Android device. As Android OS itself lacks the native support for AirPlay and DLNA, the user has to get media player App with AirPlay and/or DLNA support from Google Play. While there are free AirPlay /DNLA player Apps, majority of those free Apps require the In-App Purchase in order to AirPlay or/and DLNA feature and some of them require the device been rooted.
For some crazy reason, Sabrent implemented WiFi in "host mode" only. So you have to directly connect to Sabrent as a wifi hub. So you can't see any other airplay devices in your home (I have four others). So it's worthless if you have more than one zone, and worthless if you want to be on your INTERNET.
One last thing is to press Airplay and connect to SABRENT_a340. You can then connect a 3.5mm cable to play it through a speaker or straight to your earphone/headphones. It would be nice if a 3.5mm cable is included in the box but it is not so you have to provide your own.Pros:- It doubles the range of Bluetooth.
When you then connect to the Sabrent's WiFi network you will have Internet access. Unfortunately AirPlay doesn't seem to work on Internet connected WiFi network - you still have to connect to the Sabrent's own WiFi network... but the receiver does remember the network if you unplug it then plug it back in.NOTE: I was sent a free product sample for review.
And in the car, you can't connect to the internet while using it, so no Pandora or any streaming, can't use Maps, email, text, etc.So unless Sabrent offers a firmware upgrade to fix this silly poor design, it's unusable for my purposes. Bluetooth would have been a far better option to get around all these issues, but alas no Airplay.
This is an interesting device in that it is like a Bluetooth receiver for playing audio but instead it uses WiFi and DLNA and AirPlay.You power it via a USB power source (like a power bank, PC USB port, or USB charger) and it creates a wireless WiFi network that you then connect your device to. You can then send audio to it through DLNA or AirPlay. It's quite small and lightweight, and has no built-in rechargeable battery.
Bought it to listen to podcast and music in my car. It works as advertised, but I find it less convenient than Bluetooth. First, the device creates a wireless hotspot so your IOS devices can connect to it, but that takes a while to connect. Once your device connects to the wireless network, it automatically detects the AirPlay capability. you need a standard 3.5mm audio jack to connect to the AUX port of your audio system.
This little WiFi receiver is a niche device, designed to use with Apple AirPlay. It has a diameter just over 2 in. and an attached USB cable about 3 1/2 in. long.I plugged it into the the USB port on the rear of aGrace Digital Bluetooth speakerand then connected an audio cable from the speaker to the 3.5 mm jack on the receiver. Then it was easy to connect to the receiver by WiFi to stream music.
Answer: AirPlay? sorry. I'm android user so, I don't know about iPhone's... .. anyway I did't input any code. Just power on(insert usb port) and connect by wifi then I connected my phone to sabrent. .. And play. That's all.
