OpenGD77

Hello,

is it possible to add the feature to make our own sound beep for rx and tx start/end? For example on my Anytone I made to sound it like motorola dmr stations. I know there are some sound limitations, but on the other hand, we can make custom sound for turning on the station, so probably this feature is possible?

I have another question, are you going to make on rt3s/380/390 any larger fonts or maybe colour screen, because it has much more space and options as gd77 or similar models...


thank you for your time developing this fw.

No.

Custom beep sounds are not supported

I know it's not possible at the moment. Is FW limited to add this feature or there is to much code to be corrected? i'm really interested in this project so i'm looking forward. Thanks for all the good work and effort you put into.

Hello - as i can se in the source code, this can be corrected manually in it

Yes. You can recompile the firmware to have different tones, but thats not the question you asked.

Most people do not want to modify and recompile the firmware

Also, the source code you found is not the current source code, its a copy of an old version, which someone put on github

The latest released sources are here

downloads/releases/

Source code had to be removed from github for legal reasons, and the copy you found has an incorrect / invalid source code license, dating back 2 years ago when the legal problems occurred.

Do you mind if we put the source back and keep it updated?

Hello - i found that it's possible to change beeps, but for example if I download latest bin file, how can i open the file, to open it. I have no experiences with... thank you for your help in advance

You need to compile your custom binary now

There are two possibilities to change what you want:

a.) load the source code, modify the source code to your requirements,
compile the source into a binary, load it into device - and check if it's working
Good luck !
b.) you can load a .bin file with a hex editor, try to find the location in the binary
that -maybe- are the bytes for your planned modification, modify, load into device
and verify if it's working. But such an approach needs a deep understanding of
the binary you try to hack.

a.) is for developers, b.) is the way 'hackers' will do it. Developers can't help you,
for b.), because they never poke in their own compiled binaries, they do it as in a.).

If we can look at and compile custom binary, either this source code is complete and can be compiled by anyone or its closed source project provided free as in beer.

See the FAQ.
