Radio: Activating Semi-automatic station search up/down (Seek) w/ SWC - MTCB Software Development

Is there a way to assign "Semi-automatic station search up/down" (from pg. 18/29 of Joying "User’s Manual for Android 4.4.4 Head Unit GPS navigation system.pdf") to a steering wheel button instead of having to touch the screen button while driving? The only Steering Wheel Control button options are prev/next station preset or prev/next tuning frequency.
Edit: Or obtain what code can be sent to the radio via keyboard, SWC, etc. to activate the Seek+ / Seek- functions.

Ideally I want to map it to a steering wheel control button not "by pressing the buttons on the front panel of the radio".
I want to activate the radio's SEEK+/SEEK- from my steering wheel button. Presently I have to reach over to the radio to do it (and the radio app may not be up) and ideally I do not want to have to take my eyes off the road to activate my most commonly used head unit functions.
Alternatively, I may have to look into mtc-keys and see if I can map the two radio panel buttons to activate the radio SEEK+/SEEK-.
Thanks.

mtc-keys can remap SWC

How do I get the actual event code (touching the Radio App's on-screen button) that activates the SEEK+/SEEK- so I can map that event to a hardware button?
Presently no hardware button activates the Radio App's Semi-automatic station search up/down (Seek).

Explore the link I have posted above. Look under Radio section under the mtc-keys section
Sorry, finally had some free time today. Tested the codes(and variants) on my unit, could not get them to work. Everything else with mtc-keys has been great.
Maybe Tasker could be a solution? Have a task "Run Shell" with "input tap xx yy" Export as an App, then have mtc-keys launch it

Exactly. I did some XY development this way on my Nexus 7. Problem with the JYHU is that their Settings app does not have SERVICES under Settings->Accessibility (see my threads on this here ) which prevents, among other apps, Tasker from running some profiles. But Input XY will probably be OK.

---

The MTCRadio app is worst than I thought. Tasker input tap xy will click the radio buttons, the on-screen button will change color to indicate it is pressed, but they will not respond. The MTCRadio seems to be run from ONLY the MCU HW and will only respond to physically touching the LCD screen, a hardware button or a mouse cursor/button. If you plug in a physical keyboard, the only keys the MTCRadio itself will respond to are the left and right arrow which interestingly scrolls the entire presets block left or right. That's it. Even a keyboard's volume keys do not actually make the radio volume change. Tab keys don't work. Only keys that are mapped to the MTC steering wheel learning functions will work.
This app is hardcoded with no hooks outside of the MCU side of the headunit.

On the MTCRadio app:
I am able to use Tasker (using input tap or swipe x y execute root command) to click any of the 6 shown (per screen) radio presets buttons and it works.
I am able to use Tasker (using input tap or swipe x y execute root command) to click the stereo (ST) button and it works.
But it will not work on the SEEK+ or SEEK- buttons even though I can see the element is activated. Why are these two buttons so different than any other???
Anyone wanna give it a try (holds down for 800mS):
Launch App: Radio
Wait: 2 second
Run Shell: input swipe 910 270 910 270 800

Finally got something that works. Now I just have to configure mtc-keys to call my two standalone apps (SeekMinus and SeekPlus) when I press the prev/next keys on my steering wheel.
What I'll try in morning:
-Install folder/file mtc-keys/mtc-keys.ini
app_59=com.xxxxx.xxxxx.seekplus
app_58=com.xxxxx.xxxxx.seekminus

---

I got it all working. I had to install mtc-keys/mtc-keys.ini on the external SD card.
I made four apps: two that launch the radio first, small delay then SEEK+ or SEEK-; two that just click at the screen coordinates of the SEEK+ / SEEK- button locations.
I just have to decide whether I should launch the radio first or not. If I were to activate the SEEK+ on my homescreen it would launch one of my widgets. But it is pretty difficult to accidentally activate SEEK+ the way I have it (requires long press...something not likely to happen).
This would be so much easier if they would just add the radio's SEEK+ and SEEK- to the steering wheel control.

Hey JEMshoe, what was the trick to get 'input tap' to work on seek buttons?

---

It (input tap or swipe) won't work on the kind of SEEK+/- button elements used in the MTCRadio app. What I came up with is a kludge:
-I bought an app called RepetiTouch (kinda expensive at 12USD) and recorded the button press--save as RepetiTouch file;
-I used RepetiTouch as a plugin to Tasker and called the button press file from within Tasker; saved that as a standalone app;
-I remapped my steering wheel buttons to two functions in the mapping app that will not likely use (answer and hangup);
-I used mtc-keys to call the tasker standalone apps when it received the keycodes (69 and 70).
So now I have the ability to cycle through presets and do SEEK+/- from steering wheel buttons and tune up/down still from the right knob (which I will probably never use). This will be very nice for me during long travel so I don't have to mess up my saved stations--just go to the next/prev strong station, nor reach way over to touch a tiny on-screen button. It's been a long quest for this functionality. No help from Joying. Good leads from XDA!
Edit: Which reminds me...I need to thank the creator of mtc-keys. It worked well once I figured out that on my system it only works if I load the file on the external SD card.

Have you tried something like:
mtc-keys.ini
Code:
event_59=22
event_58=24
That worked for me.

I have a stock HU (Hotaudio Model HA2100) and I have the same problem of you.
SWC: It seems that if I configure "<<" or ">>" as buttons, pressing it on the steering wheel the Radio the frequency is changed by few KHz... (No search is started). if I configure "<I" or "I>" as buttons, pressing it on the steering wheel the Radio move to the next stored station. (No search is started).
For what I understand installing mtc-keys and configuring the mtc-keys.ini as before, I should solve the issue, isn't it ?

royalhawk, give it a try and report your results. I don't recall everything that I tried but unfortunately I now have a *couple of layers* between my controls and the headunit that would make evaluating this difficult.
*couple of layers*: I have mtc-keys.ini used for some functions, I also have a custom app that gets called to simulate pushing the seek+/- button and finally I also have a piece of custom hardware that extends the functions of some of the existing steering wheel buttons. I would have to undo these (at least temporarily) to evaluate the suggestion from jakejm79--which would be great! if it works for me/my setup.

Hello,
I don't know if I'm in the right section.
It's possible to teach the radio long press actions on SWC?
My old AN-21 could do this but my Pumpkin Unit don't or I'm wrong?
Best regards
