cjgu00 commented 3 years ago

Hi!

I am really interested in this utility. It should be very useful. I try ble-serial on win10, but fail. Why? com0com_setup

Please help me... Thank you!

Hi @cjgu00, have you rebooted the system after the com0com setup?

cjgu00 commented 3 years ago

Hi, Jake!

I DO reboot my notebook after installed and configured the com0com. But it was the same anyway. Is there any others to setup or to config?

Hi, Jake!

I tried the same thing on another computer. It did work! So it should be the problem of my computer settings. Though I don't know what the problem is. Sorry to bother you and thanks anyway!

Very nice! If you figure out sometime what setting it caused then please mention it here, to help others that might encounter the same issue. I mark this issue as closed now, but you can still answer.

I have the same problem but I didn’t know how to solve it at the time. @cjgu00 @Jakeler Can you help me?

Jakeler commented 3 years ago

@lautumn1990 You could try a few things:

run ble-serial with -p COM9 (or any other port you have on the system)
check if miniterm can connect and transfer data
- python -m serial.tools.miniterm \\.\BLE
- python -m serial.tools.miniterm COM9
check if the virtual ports work from other terminal programs, for example ScriptCommunicator
delete the port pair, reboot, set it up again, reboot
change system settings, for example if you have set Windows to Chinese language try English (maybe it is somehow related to character encoding in paths)

Please report back what you find. If nothing works we could make a minimal example and open an issue upstream, though I probably can't help much because I am unable to reproduce this error...

Hi!

Finally, I found why I failed on the 1st computer but succeeded on the 2nd one! The 1st computer is a pretty new one of my friend. I missed the following note because I had no idea what is 'secure boot'. Maybe some words about that could be helpful for newbies like me.

After fixed, the new computer could run normally.

The 2nd computer is my old computer. It didn't have 'secure boot' option. So it could run without changing any settings.

Hope this can help!

lautumn1990 commented 3 years ago

Great, it took effect after disable the secure boot option. I also missed this note. I thought it was not relevant. When I changed the settings from the BIOS, everything was normal. @cjgu00 @Jakeler Thanks a million!

If anyone has a similar issue, in my case it seems that it was the ble-com-setup.exe not working. After I manually set a pair in Com0Com and named a device BLE, it would work
