(...) Moreover, what's being asked above is about development on both the radio side but also the "hotspot" side, which has never been the focus of this development and this forum. I suggest my fellow Canadian ham to seek that level of commitment from the hotspot platform people instead.

And I thought this thread is about the new Radioddity GD-88? Please don't hijack the thread, thanks!
David VE7MDT,
OpenGD-77 has a Hotspot feature that is already part of the project as well as other features that other developers found personally interesting.
The firmware has a hotspot function and the forum has a topic to discuss it. If you judge this negatively, it is your choice but do not decide for the others which functions are at the center or not of the development or which are more relevant than others. Many have repurposed the GD-77 as a Hotspot and mostly like this feature.
It is obvious that if the GD-77 allows to go on D-Star, AllStar link or echolink, to name only those, that the community would greatly appreciate.
The proposal discusses, among other things, the HotSpot function already present since it uses the same connection with the same Raspberry Pi and some identical applications in order to extend the functions of the GD-77 even more.
Firmware suitable for Raspberry applications could extend functions and capabilities to several levels. But you probably already understood that.
Improving the functions of the GD-77 had never been approached from this angle. Why decrease that?
Sincerely sorry for having taken the trouble to answer Roger as best I could, in my second language, in order to make myself understood. Now, Roger and I know that the principle (idea) is possible but that it takes the investment of someone who has the time since it is currently not a priority for him.

You will notice that in this subject the majority of your interventions concern other radios than the GD-88 or even digital radios. :lol: ;)

Thank you for your understanding and respect! Let's stay constructive and positive!

The topic regarding: ''Proposal GD77 Multimode + Web Transceiver'' will continue here: https://opengd77.com/viewtopic.php?f=7&t=2348 in order to respect the initial subject which, inadvertently, branched off to the subject of the development of the GD77 which had not yet been approached from this angle and which is still THE subject of the forum.

Sorry for wanting to clarify this great opportunity in this topic to make sure we all understand each other and thank you for your understanding! Let's stay positive and good development! We will continue elsewhere.

Why don't you continue to post here for us to learn from you then?

As for myself, I am out of here. You now can own the thread.

This thread has been moved to the Off Topic section because of complains from multiple forum members that this is an off topic post and show therefore not be in General Discussions relating to the GD77

This forum is only to help people support each other in the use of the firmware, and for the developers to announce when there are updates to the firmware.

Mostly everything else is off topic, but we do also try to help people who are new to DMR understand how to use their hotspot as well as how to use the firmware.

Does anyone know what hardware the GD-88 is based on?

What CPU(s) / DMR / VFO / etc. and if it single or dual rx / tx hardware?

Hi!
I don't know anything about internal details, it's not stated anywhere, but I've got the radio this week, and I can confirm, that it's really dual RX. About the CPU, I have only one trace - the programming cable contains Prolific PL-2303 USB to serial converter, so the CPU is probably different from those we can use for running OpenGD77.

With regards & 73

Here you can look inside this radio:

what I can tell from the photos of the internal of the GD-88 is that it has two (C7000) processors and from the report of a current owner two RF receive circuits (paths).

Might be an impressive radio, but I doubt there will any independent 3rd party firmware for this radio any time in the near future.

For now I will keep using my C6000 based radios running the various implantations of OpenXXyy.. firmware.

There is nowhere near enough documentation on the C7000 to be able to write firmware for it.

Also the CPU inside the C7000 uses a Chinese designed C-SKY processor core, and there is only limited support for this outside of China.
I think there is now a version of the GCC compiler linker toolchain that will work with some C-SKY CPU's but there are different models of C-SKY core, and its not know what is inside the C7000 and whether there is a compiler for it.

I don't think the Openxxx firmware will ever run on this radio, or any radios that use the C7000, combined DMR and CPU chip.

I got my GD-88 last week. My expectations were high - I wanted to see a better successor of famous GD-77 I own and am happy with.
Yet the bigger was my disappointment. Crappy CPS, crappy firmware, overall disappointment considering the (not so low) price.

Anyways I am open to any discussion and even hacking :)

My observations regarding the radio itself:
- Alternate CPS editor is built by MM7DBT: https://www.cpeditor.co.uk/ and works great.
- In APRS, the radio identifies itself as "Anytone: AT-D878 (ht)" (see my station report here). Yet I am new to APRS so no idea what this exactly mean. EDIT: reason is that by default, TOCALL in analog APRS config is defined as APAT81 which results in this.

I have a lot of other thoughts regarding usability, build quality and overall performance, but this is perhaps more for a pub chat as it will end up as a rant on chinese radios.

EDIT:
I contacted Radioddity support with various questions. Only thing they helped me with is an issue with connecting of default CPS failing with message "Data Mistake". Reason is, ridiculously, too high COM port number (my case was COM16). Changing it to lower number (I tried COM4) did help.
