Hello @ArtemTomin , it looks that the script cannot communicate with your Arduino on the port you specified.
I just pushed some changes on master that enable auto-detection. This means that cc_*.py
scripts will now auto-detect where is the CCLib_proxy
connected. Can you try updating to the current latest version and trying again, without specifying any -p
or CC_SERIAL
environment variable?
Dear @wavesoft, The some problem, but o lil bit different error: ERROR: Could not detect a CCLib_proxy connected on any serial port
Hey @ArtemTomin ,
It looks that there is a problem with the pyserial
library. I think I have fixed it on the current master (just pushed another commit) can you try it and let me know?
Hi @wavesoft, Thank you for such urgent help. But, unfortunately, it still doesn't work. Now, after ./cc_info.py or ./cc_info.py -p /dev/cu.usbmodem1411 just no reaction. Just is blinked cursor.
Hey @ArtemTomin , do you see the Arduino LED standing still? If yes, can you try unplugging & plugging it again?
Also, try to use the latest Arduino library. I just pushed some changes that prohibits this lockdown from happening again.
Hi @wavesoft, Should I try with connected CC device, such as BLE112? Now, the some trouble. But i didn't connect any device, only arduino UNO. Did you see my screenshot?
Hey @ArtemTomin , unfortunately I can't see your screenshot. You don't have to have a CC device connected to get a handshake confirmation. You should get a warning regarding wrong wiring. Are you sure the Arduino sketch is the correct?
Hi @wavesoft, I use simple Arduino UNO, I've uploaded your sketch from Example folder without any changes.
Ok, that's interesting. I from the port name I guess you are on Mac OSX? Which version? And which Python version are you using?
Can you also try to do a manual ping to see if there is something wrong? You can type the following:
~$ dd if=/dev/cu.usbmodem1411 bs=3 count=1 | hexdump -C&
~$ echo -ne '\xF0\x01\x01\x01' > /dev/cu.usbmodem1411
If everything goes well you should see something like this:

If not, something is wrong with your set-up.
I see this: [1] 24406 iMac-Artem:~ Artem$ 1+0 records in 1+0 records out 3 bytes transferred in 0.000024 secs (125829 bytes/sec) 00000000 41 69 38 |Ai8| 00000003
[1]+ Done dd if=/dev/cu.usbmodem1411 bs=3 count=1 | hexdump -C
When I try to connect with ./cc_info.py -p /dev/cu.usbmodem1411 I see just frozen cursor. If i disconnect Arduino, i see immediately ERROR: Could not find CCLib_proxy device on port /dev/cu.usbmodem1411
The response that I see there does not really look like the one that I would expect from the sketch. Are you sure that's the correct port? Could it be that there are 2 ports for the arduino board? One for the bootloader and one for the serial port?
I haven't used an Arduino UNO, so I can't say for sure.
I use OS X El Capitan. Python 3. Yes, this is correct port, i use it other my application with arduino and it works fine. There is only one port. My Mac see this port and bluetooth, that all.
Hey @ArtemTomin , that looks like ASCII output. Can you try connecting using the Arduino Serial Monitor, type something random and hit enter? We might get something more useful out of it.
Hi @wavesoft ! I did it, speed is 9600. Response is just ????????? Unreadable symbols.
Hello, @wavesoft, I have the same problem as @ArtemTomin, but I use OS Windows for this. The symptoms are the same - when I launch cc_info.py I get a frozen cursor and when disconnect USB cable out of Arduino UNO, it says ERROR: Could not find CCLib_proxy device on port com14. I use Python 2.7, Win7 x64, Arduino UNO, the sketch is without any modifications - as in your library. I am going to flash BLE113 - so I could test the solution for CC2541. Urgently need help. Thank you.
Did you ever get this resolved? I am running into the same issues. It seems that the proxy is ok when I send manual commands using Realterm. Maybe this in the version of pyserial that is used.
Before digging further, did anyone get this resolved?
I have the same problem using a Wemos D1 mini. Tried two different MacBooks and different versions of pyserial. How can I debug this?

The originally raised IOError is ERROR: CCDebugger responded with an unknown status (0xa4)
where the status changes (b4, c8, c8, ca, b4, b2, 30, ...).
Tried pyserial 3.0.1 and 3.4. Python is 2.7.15.
Tried it on my Windows PC and it works 🤔
At least the Wemos D1 mini replied correctly right away.
For it to be able to talk to the CC2531, I had to add the -E
option - before that I just got No chip found. Check your connection and/or wiring!
.
@vogler, can you explain or write the whole line where you used the -E
?
@wavesoft, I have spent a few hours, but all I get on my Arduino Mega is this:
ERROR: Could not detect a CCLib_proxy connected on any serial port
I just flashed the BLINK-code to make sure the Arduino works, it does.
When I call cc_info.py the LED flashes like 2,5 times and then dark. Here ^CERROR:
I hit Ctrl+c after couple seconds.
How could I dig deeper to see at which level it gets stuck?
Another way to debug?

@tido Since Windows' cmd doesn't persist history I can't look it up, but I think it was just what I wrote above, i.e., python2 cc_info.py -E
.
I tried to get it to work on macOS before, but that somehow didn't work.
https://github.com/wavesoft/CCLib/blob/master/Python/cclib/ccproxy.py#L134 From your output it seems like with Python 2 this line blocks, while with Python 3 it throws. Maybe print those exceptions to debug.
@vogler, thank you for your quick reply. I tried it with your line.. still doesn't work. Line 134, you mean to change the python code so, that it prints more details, than just the line @wavesoft defined? How would you change the code ... I only read a book about C.
It looks like that wavesoft has abandoned, this neat work of his, two open commits are not merged.. if I am not wrong. I looked now at the FORKS and this: https://github.com/kirovilya/CCLib was reForked a couple times and even in 2019 accepted commits.
Then I would try this fork - the commits say it's adjusted for Python 3. https://github.com/wavesoft/CCLib/blob/master/Python/cclib/ccproxy.py#L138-L143 You could just remove this try/catch to see which exception was thrown originally.
if you have a Raspberry Pi (I am not a fan) you can just connect it and flash it. I wasted hours on the Arduino /ESP32 ideas. This just worked: https://github.com/jmichault/flash_cc2531
Hi, I also struggled some time with this problem (Windows 10 64 bits) Pyserial is installed! python C:\Users\etadmin\Downloads\CCLib-master\CCLib-master\Python\cc_info.py NOTE: Performing auto-detection (use -p to specify port manually) INFO: Checking COM11 ERROR: Could not detect a CCLib_proxy connected on any serial port
This starts python3 on my computer! After installing pyserial for Python27 C:\Python27\python.exe -m pip install pyserial==3.0.1 (updating pip C:\Python27\python.exe -m pip install --upgrade pip)
it works C:\Python27\python.exe C:\Users\etadmin\Downloads\CCLib-master\CCLib-master\Python\cc_info.py -p COM11 INFO: Found a CC2530 chip on COM11

With this resolved I could follow the instructions on https://github.com/arendst/Tasmota/wiki/Zigbee

On OSX I could solve this by adding:
self.ser.reset_input_buffer()
self.ser.reset_output_buffer()
after time timeout in the routine that opens the serial port.
Apparently there are some characters in the input/output buffers. The current code does´t know how to 'align' itself so clearing the buffers helps here.
