Add cw and sstv decoder

[Hack228pro]

Hello, I saw in the firmware a spectrogram and other parts for visualizing sound. Is it possible to add at least a Morse code decoder?

[EmEiBee]

As far as I know, there's no connection between the receiver's audio output and the ESP. Therefore, decoding with the ESP isn't possible unless you provide the audio data to the ESP via additional hardware.
Please correct me if I am mistaken here...

Huh? What are you supposed to do with it without any description? Will it become a washing machine?

The audio output is not wired to the CPU. The Scan feature uses RSSI; waterfall and other sound analyzers are just cool hacks made by Sergey - they use battery voltage level as a proxy for the audio speaker current consumption.

I'm not going to add these hacks to the radio firmware

they use battery voltage level as a proxy for the audio speaker current consumption.

Really? That's weird ;)
Okay, you can do that, but you'd be hard-pressed to achieve even rudimentary accuracy here, considering how inconsistent the Wi-Fi module alone is in terms of power consumption... Funny ;)

http://www.hjberndt.de/dvb/pocketSI4735DualCoreDecoder.html has the firmware with a variety of decoders, to properly do it you do need a simple hardware mod. the downside for me in that firmware is that it doesn't support themes but otherwise it's a nice one. He personally describes it as a personal firmware and refers to this repository as probably more usefull to most.
I'll just keep my fingers crossed someone is going to add those options to this firmware.

These kind of features are the ones I'd be willing to pry my unit open for.

Oh than you'll love the update he did today. Rtty decoding and all sorts of upgrades. such a shame it's closed source. But he is actively developing

[jmi2k]

Oh that was today? I just discovered that FW a few minutes before posting my previous message!

Yes, such a shame source is not available, hence why I'll stay on this one for the foreseeable future (also, the UI doesn't feel as crammed and improvised, which is also appreciated).

That's why I keep switching back and forth. :(

Some folks buy multiple ATS Mini receivers (different hardware versions, different case materials and colors) and install different firmwares on them.

FYI: you can decode the digital modes on a smartphone using a special adapter that converts the receiver headphone output to the smartphone mic input. The setup is quite portable and doesn't require a computer. I made the following adapter in 2024:

(before that I used iRig Pro I/O soundcard to feed audio to my iPhone, but the adapter is a much simpler solution)

I believe it is possible to purchase an adapter like this from HeadsetBuddy, but I didn't try it myself (please let me know if it doesn't work). More info on the accessories page: https://esp32-si4732.github.io/ats-mini/accessories.html#line-level-to-smartphone-mic-adapter

Would you mind telling what app it is. for the likes of it I can't find it

[max-arnold]

That is iFTx for iOS. On Android people use FT8CN
