Rtl sdr on android

Краткое описание:
Позволяет слушать радиоэфир в очень широком диапазоне.

Описание:
Приложение предлагает удобный интерфейс для использования китайских USB TV-тюнеров в качестве радиоприемника, способного принимать что угодно в диапазоне 60-1700 МГц (радиостанции, звуковое сопровождение ТВ, радиолюбителей, карманные радиостанции, переговоры самолётов с диспетчерами, строителей, такси, жучки в вашей квартире и многое другое).

Для работы с приложением необходимо:

устройство с поддержкой USB-host
совместимый USB TV-тюнер
драйвер для подключения тюнера (устанавливается отдельно; само приложение предлагает скачать из Play-маркета от того же автора)
для устройств с версией Android младше 3.1, а также в исключительных случаях — root

Устанавливаем SDR Touch и приложение-драйвер, подключаем тюнер, нажимаем кнопку OFF, подтверждаем — можно слушать эфир.

От используемого тюнера зависит широта доступного для прослушивания диапазона.

Я тестировал на SGS3 4.1 с тюнером Terratec T Stick PLUS (E4000+2832U).

Для Pro-версии нужно покупать индивидуальный SDR Touch Key. Появится возможность просмотра спектрограммы (водопада), RDS монитор, запись аудио.

Русский интерфейс: Да (если есть замечания или ошибки по переводу на русский, пишите мне в QMS

Приложение-драйвер для тюнеров от автора SDR Touch можно скачать в Play-маркете либо с GitHub (прикрепляю оттуда).

Using the SDRplay and SDRTouch on an Android Mobile Phone

A few months ago the popular SDRTouch software for Android added support for the SDRplay RSP. The RSP is a $149 USD software defined radio with a tuning range of 100 kHz to 2 GHz and a 12 bit ADC.

Over on YouTube user Mile Kokotov has uploaded a video showing the SDRplay RSP running in SDRTouch. He uses it to listen to the 14 MHz ham band in SSB mode and finds that reception is clear and that it is fairly easy to tune around.

In order to use the RSP with an Android device you will need a fairly modern phone and a USB OTG cable. Ideally try to get a USB OTG cable with an external power port as the battery can drain quite fast when using the SDR. SDRTouch also supports the RTL-SDR.

I agree with Skip. That was my experience – in connecting my SDRPlay to my HP Touchpad tablet (running Android 4.0.4 via Cyanogenmod). The tablet would not go into USB Host Mode unless I had the USB Y-cable connected AND an external power source too. I tried the powered USB hub first, and then a USB-battery. Both worked. I removed the external power from the cabling – and it failed to work. I LOVE the simplicity of the SDRTOUCH app coupled with the amazing SDRPlay device. Really great combination! 🙂

It should be noted that the SDRPlay draws less than half the current than an R820T based RTL dongle (120mA vs. 250mA). However, both work fine on my Samsung S3 via a standard OTG cable without external power.

A USB battery pack and a OTG ‘Y’ cable are really needed for portable operation, along with a
power-rated USB cable. Otherwise funny things happen.

SDR Touch brings RTL-SDR to Android

SDR Touch is an Android app which allows the rtl-sdr dongle to be used on an Android device. A USB OTG (on-the-go) cable is required to connect the android device to the tv dongle. The blurb on the app authors website reads

(SDR Touch) Turns your mobile phone or tablet into an affordable and portable software defined radio scanner. Allows you to listen to live on air FM radio stations, weather reports, police, fire department and emergency stations, taxi traffic, airplane communications, audio of analogue TV broadcasts, HAM radio amateurs, digital broadcasts and many more! Depending on the hardware used, its radio frequency coverage could span between 50 MHz and 2.2 GHz. It currently demodulates WFM, AM, NFM, USB, LSB, DSB, CWU and CLW signals.

If you do not have an rtl-sdr dongle yet, you can find a good place to grab a compatible one for about $20USD from the Buy RTL-SDR page.

Currently, it seems that USB, LSB, CWU and CLW are experimental and may not fully work. In a recent update squelch, gain and offset control have been added to the app. SDR Touch is still early in its development and as such many features may still be missing. A list of upcoming features and supported tuners are shown on this developers forum thread on xda.

Most newer devices with Android 4.0 or higher should work with SDR Touch. Devices with older versions of Android may work if rooted. Some Android devices also may not provide enough power through the USB port to power the tv dongle. A USB OTG cable with an extra power port may be required to power the dongle. An extra power port may be a good idea regardless, as an app like SDR Touch is prone to draining the battery fast.

SDR Touch has been having some licensing issues which has resulted in its removal from the Google Play store. It can still be downloaded for free from the authors website. Upgrading to the Pro version for £5.99 removes a trial timer on the graphical spectrum viewer feature.

A lot of people seem keen to use SDR Touch as an Android in car radio on their tablet. The SDR Touch author has promised to integrate more features such as a Frequency Manager which will help with this use.

Here is a test with a rtl-sdr R820T dongle on a HTC One X Android Jellybean phone

New RTL-SDR Driver for Android Developers

Android developers have a new RTL-SDR driver wrapper available to use called «RTL-SDR CP Driver». This driver by Evgeni Karalamov is designed to have an additional feature over the current Android RTL-SDR drivers in that it implements client application permission management. The overview reads:

RTL-SDR CP Driver utilises the rtl-sdr codebase and is meant to be kept in sync with the developments there. The provided interface mirrors the functionality of rtl_tcp in an Android way. Instead of via a TCP socket, the communication is carried out through file descriptors returned by a ContentProvider .

Since some potentially sensitive information could be captured through the SDR receivers, like indications of the device location, the RTL-SDR CP Driver implements permission control similar to that of the Android framework. Prior to accessing receivers, client applications have to ask the user for permission to access the driver by starting the driver’s permission flow via startActivityForResult . Once the user grants access, their answer is remembered and they are not prompted again. The user has the ability to later revoke the permission from the driver’s UI, accessible via the Android launcher.

The actual driver app can be downloaded from the Google Play Store. Note that this doesn’t provide any functionality by itself. We will need to wait until apps take advantage of it.

Make a functional app for chromebooks and I’ll be happy.

Does this driver allow direct sampling?

It allows what rtl_tcp in version 0.6.0 of rtl-sdr allows, which includes direct sampling.

Could we have a python intepretter that can use this?
