I edit the message, i thought I had found a race condition while looking for a next channel but it is not the case.

Re: serial data with internal mic and speaker

So if I need to open the radio to solder some wires, appart from the USB connection is there another (free, not used during normal operation) bidirectional interface we can use to communicate to the outside world? (i2c, uart....) And now my crazy idea just in case you want to know what I am looking ...

Re: serial data with internal mic and speaker

Before cutting any wires I will try to find the jacks in an electronic components store, do some testing and if it works build a connector with the 3d printer. Is this drawing right? if it is, then the data+ is in the tip of one of the connectors, I hope it is not the one that mechanically switchs b...

serial data with internal mic and speaker

How is the internal mic and speaker disabled when you connect a mic to the gd77? Is there a mechanical switch? Is it possible to modify the connectors, maybe by removing the tips to make them shorter, so one can use the internal mic and speaker and have serial data at the same time?

Re: White noise after changing slot

I have created a PR with changes to keep track of the amp ussage. I have abused commenting lines where the amp pin is changed instead of replacing the lines with calls to the new ampEnableDisable function. Let me know what you think and I can clean the old commented code.

Re: Update 16th Feb

With the latest version there is an audio quality drop in my gd77, it sounds like metallic and with some noise.

Re: White noise after changing slot

Nice explanation. There are like 15 places where the amp pin is set to 0 or 1. We can create a new function to enable and disable the amp that receives as parameter if it has to be on or off, and the type of audio: beep, digital/analog (do you foresee we will have to differentiate dmr and analog?) T...

Re: White noise after changing slot

Interesting theory, something worth investigating, maybe we need to add a close audio call after the key beep

Re: White noise after changing slot

It still happens to me too. I have tried using the methods init_sound() and init_digital() when changing slot. Both methods are used when changing the channel. Using them when changing the slot did not produce the expected results. it is not really anoying at all, I can only hear it when at home in ...

Re: Reset when scanning

I will try to reproduce the problem and review the code, unfortunately even if it can be reproduced there is a lot of guess work as the debug options are minimal. What would be the best way to send some information via the serial port?
