Internet radio and podcasts on your Anbernic RG40XXH (muOS), with the screen off

A retro handheld makes a surprisingly good little radio: it has speakers, a headphone jack, Wi-Fi and a battery that lasts for hours when the screen is off. PocketKode Radio turns your muOS handheld into exactly that: thousands of internet radio stations from around the world and podcasts you can stream or download, all with the controller. This guide shows how to set it up and get the most out of it.

Tested on: Anbernic RG40XXH · muOS 2601.0 Jacaranda · PocketKode Radio 2.0.1.

Step 1: Install PocketKode Radio

1. Download PocketKodeRadio-<version>.muxapp from the PocketKode Radio page (no account needed).
2. Copy it to the ARCHIVE folder on SD card 1 (with a card reader or Wi-Fi Transfer).
3. On the handheld, open Applications → Archive Manager, select the file and press A.
4. Turn on Wi-Fi (Configuration → Connectivity → Wi-Fi Network), then open Applications → PocketKode Radio.

Step 2: Find a station

Open Radio. The stations come from Radio Browser, a free, community-run directory with tens of thousands of stations.

Menu	What it’s for
Top stations	The most listened-to stations worldwide
By country	Every country, A to Z, with its number of stations
By genre	Pop, rock, news, jazz, talk and many more
Search	Find a station by name with the on-screen keyboard
Favourites	The stations you saved
Recently played	Your last 15 stations

Two tips:

• Press Y on a station to add it to Favourites, so you find it again in one step.
• In By country, press Y on your own country to make it My country: its stations then get their own entry at the top of the Radio menu.

Step 3: Now playing

Press A on a station and it starts playing. Many stations also show the song or show that’s on air.

Button	What it does
A	Pause / play
SELECT	Add to favourites (radio) or download the episode that’s playing (podcast)
START	Screen off
Y	Sleep timer: 15, 30, 45, 60 or 90 minutes, or off
X	Stop
B	Back to the menus: it keeps playing
◀ / ▶	Podcasts: back 15 seconds / forward 30 seconds
L1 / R1	Podcasts: speed

For the volume, use the handheld’s own VOL+ / VOL− buttons. Now playing shows the volume at the top right, and “Sound is off: press VOL+” when it’s at 0 or muted.

While something plays, a bar at the bottom of every screen shows it. Press MENU to jump back to Now playing.

Step 4: Turn the screen off to save battery

The screen uses most of the battery. With it off, the handheld plays for much longer:

• On Now playing, press START.
• Or on the home screen, choose Turn off the screen (it’s there while something is playing).

To turn it back on, press START or MENU. Other buttons don’t wake the screen, so a button pressed by accident in a bag or pocket doesn’t wake it, pause the radio or change the station. The volume buttons keep working.

Combine it with the sleep timer (Y) and the radio switches itself off after you’ve fallen asleep.

Step 5: Podcasts

Open Podcasts:

• Search for a show, or browse Top podcasts (Apple’s public podcast charts; pick the country in Settings → Podcast charts).
• Press Y on a show to subscribe: your shows are in My podcasts.
• In a show’s episode list: A plays, X downloads (press again to cancel or delete), Y marks as played.
• Downloaded episodes play without Wi-Fi: download a few at home, then listen anywhere.
• On Now playing, ◀ / ▶ jump back 15 or forward 30 seconds, and L1 / R1 change the speed from 0.75x to 2x.
• Where you stopped is remembered for every episode.

Downloads are kept on the SD card; Settings → Delete all downloads frees the space again (your subscriptions and progress stay).

Updates: the app can check GitHub for new versions (Settings → Check for updates, on or off). Nothing is installed unless you choose Update.

Troubleshooting

• “No internet connection”: turn on Wi-Fi in Configuration → Connectivity → Wi-Fi Network, on a network with internet access.
• “Secure connection failed”: the handheld’s date and time are wrong. Fix them in muOS’s settings.
• A station doesn’t play: stations sometimes go offline or change address; try another one.
• An episode doesn’t stream: Radio downloads it and plays it as soon as the download is done.
• Accented or non-Latin names: Japanese, Chinese, Korean and Cyrillic names are shown with the Noto fonts. When the app is in English, its pixel font shows accented letters without accents. The stations play normally.
• Something else: the logs are logs/app.log and logs/mpv.log in the app’s folder. Email them to feedback@pocketkode.com with your device and muOS version.
