Re: Line In/Out Pinout to Mac

The TRRS pinout for an Android device is actually different from an Apple device. One of the things I learned yesterday. Basically the microphone for an Apple device (CTIA standard) is on the sleeve whereas the microphone for an Android device (OMTP standard) is on the 2nd ring. The ground position just flips depending on where the microphone pin goes.

I’m curious too what happens when you go from a TRRS to a TRS. Does it just mesh the audio channels together? Or just eliminates the mic? That will be the next thing I look up.

My guess its similar with most phones - I can't image how they would otherwise electronically detect the difference between a 3 connector plug (--> just headphones -->  leave the internal microphone of the phone on) or a 4 connector plug (--> switch the internal microphone off)

@Ben:

What I did:
After figuring out that my phone is alway leaving the internal microphone on (and not turning to "external" microphone aka morserino) I connected an normal phone headset which ... surprisingly worked. Then I measured the resistance of the microphone and put in a resistor for mimicking that.
Don't know about the sound quality though.

If your MacBook also has to decide if there is an external microphone connected or not and you are not receiving anything I guess its worth a try...
Maybe you can doublecheck in the sound setting the changes of connecting normal headphones vs. connecting a headset. If there are automatic changes there I guess you found your problem.

Thank you Juergen,

I verified all connectors on the board to the TRRS cable look good. So no issues there. Also in case it helps anyone else, the solder points from the previous photo bottom left moving clockwise are: ring 2 (ground), ring 1 (line in), tip (line in), and sleeve (line out).

I did overlook that part of the manual. I was able to adjust the audio in on the Morserino according to the manual. I tested that it can receive and decode morse code when generated by the computer! So, we are narrowing in on the input issue of getting the line out from the Morserino into the MacBook Pro.

Birk mentioned that maybe that Mac doesn’t detect the Morserino as a microphone. I believe that is the issue right now. I measure DC voltage across the TRRS ring 2 (ground) and sleeve (audio out) so I believe the Morserino is outputting audio voltage.

Yes Ben,

You know the automaticly switches off speakers when u pluged in a headphone...

So next what i would test with a OHM-meter: solderd connection points and the TRRS at the cable.

And then there may be an un-read point in the manual (pg 6):

....
A long press of the RED button starts a function to adjust the audio input level (and possible the output
level on a device you connected to the Morserino-32's line-out port).

Hi Juergen,

Good point. I connected the audio out to an amplified speaker and heard no audio. Tested with the headphone jack and got plenty of audio. This made me thing there might be something wrong with my soldering job or the component. Sure enough, when I tested, the two pins in the yellow box appear to be connected even when not keying. The solder joints don’t look connected, so I’m wondering if I got a bad component or where to check next. None of the other pins seem connected.

Yet when I plug the Morserino into my mac and go to the CW Keyer, I see no audio coming into the mac. When I go to the iCW function on the Morserino, I see no audio coming into the mac. I'm missing something here, but not sure what if anything to splice in the cable to make this work. Some additional insight appreciated.

Hello Birk and Ben,
when i understood it right Ben, u wrote that u couldn't "detect" any audio at the TRRS contacts, so that
we have two different reasons: no audio from Morserino and - there is audio, but the Apple do not "receive"
it. or do i see it wrong ?

Hi Birk,

I’ll have to give that a try as well. I’m not using my phone, but trying to get the keyer to send the audio into my 2015 MacBook Pro. It does detect the Morseino as a headphone device for output, but doesn’t show up as an input device at all. So maybe the resistor fix you did will help with that piece. Will let you know if that works for me.

Maybe its the same for you...

Betreff: Re: [morserino] wifi connection

Folks, morserino does not need or want YOUR WiFi connection to start.  Instead, you must disconnect your PC from your WiFi network.  When the PC is no longer connected to the network, morserino will create its very own Adhoc network.  Connect the PC to the adhoc, and while connected to adhoc, you will setyour home SSID into morserino.

Disconnect everything, and the morserino will then connect to your home WiFi.

It’s a two step process.

I can only assume that the WiFi signal from your router is too weak. Put the Morserino in direct vicinity of your WiFi router. Or did you change anything in your WiFi setup since you updated succesfully?
