Description
Just purchased this unit a few weeks ago and was hoping CHIRP would work, but alas it did not. Manufacturers software doesn't even support this radio as of yet. Help!

Is there any way I can help you to support this radio?

I attach 2 log files from serial port monitor - while reading from device and while writing to it via Wouxun original software. I wish it could be helpful somehow. If there's anything else I can do, just tell me.

I add another log of reading from this device. It seems like I should send IiNHRGc” to identify device and then data is sent in packets of length 68. I was working on existing files wouxun.py and wouxun_common.py. I don't understand do_download function from the second one. Especially line cmd = struct.pack(">cHb", "R", i, blocksize) what is that for? I always get exception in this function beacause required data length does not match real length.

Hi Piotr,
struct is a python class to interpret strings as packed binary data with a predefined format.
You can have a peek in the python docs here [[[https://docs.python.org/2/library/struct]]]
cmd = struct.pack(">cHb", "R", i, blocksize)
This is packing the data with Big Endian coding(>), "R" as char (1 byte long), i as a unsigned short (two bytes long) and blocksize as signed char (1 byte long)
For example:
i = 256
blocksize = 64
cmd = struct.pack(">cHb", "R", i, blocksize)
Then cmd will have "\x52\x01\x00\x40"
the reverse function is easy also:
CMD, i, blocksize = struct.unpack(">cHb", cmd)
Cheers

Thank you for your answer, but i still do not know what does >cHb mean. I see now that '>' means Big Endian coding, but what does the other part mean? cHb?

In simple terms: it's a handy function to pack/unpack data into a binary form, many radios have a predefined structure on the headers it's send/receive; with this function/procedure you make shorter code to pack/unpack data. As simple as that.
"<cHb" it's just the format the data has to be encoded/decoded, it's like a template to render the binary data you pass as variables, in the last post I put a translation for each term.

It's been a few years since this thread was started, but it seems the Wouxun KG-UV899 is not yet supported. It's not an option in the models currently shown in the download-from-radio pulldown, and my attempt to substitute other models failed. Is there any plan to include the KG-UV899? What needs to be done to make it happen? Many thanks...

The addition of a new radio to Chirp requires two things:
1) a volunteer developer who takes the task to work on this driver,
2) availability of test equipment, such as a loaner radio (see Rules For Loaning A Radio).
Unfortunately, you need to wait until both conditions have been met.
