@robert-hh Thanks for replying. I have try for another usb cable and port instead but the problem is still the same.

@crumble Reconfiguring P0/P1 should not affect the cisibility as COM port. The UART/USB bridge should always be registered by Windows as such, even is the ESP32 is not connected to it. So I still guess it's a driver problem. Try to reinstall the USB driver from the vendor's web site: http://www.ftdichip.com/Drivers/VCP.htm

@crumble i have try to install the driver and follow the step given. But when i install the driver it showing the driver is already update.
I try connect the pytrack in atom it stills showing the "Found 0 serial port"
May i know how to get it fix ?
-
@mj Do not use the driver method, download the driver file and execute that manually.
-
Have you updated the firmware of the pytrack?
After that mine was not detected as a com device. You are using windows, right? Please check in the device manager, if your pytrack ist detected as a com or a dfu device. I can't remember how i fixed this. I guess I deinstalled the dfu driver, so that the pytrack was detected as a com device again.
Install todays pytrack firmware, before you do this ;)
-
@robert-hh I have downloaded the driver and follow the step inside the link but still showing the same problem.
-
@crumble I have installed the dfu driver in the pycom.documentation yesterday and update the Pytrack, I also ensure that the Pytrack is in DFU mode as well. The problem is still there.
I have tried my Pytrack on my friends laptop since she only using Lopy and expansion board only. My Pytrack works on her laptop as normal but when I tried it on my laptop it stated zero serial board. I have no problem for my expansion board too only Pytrack goes wrong. This make me feel confuse and I have no idea what happen to my Pytrack.Today's dfu driver is it the latest?

@mj My PyTrack is now nón 0.0.6 as well. While libusK is installed, Windows 7 detects it as a libusK device for some seconds. You have to be quick again.
- Open the device manager,
- Plugin the pytrack. It will be listed as a libusK device not as com
- right click on pytrack
- select deinstall driver, hook uninstall driver
- rescan devices
- pytrack will become a com device

@mj this worked on my machine. Have you cecked that files shall be removed when uninstalling the driver?
Version 0.0.6 is linked in the Announcement section of the forum. The docu still shows 0.0.4 as the latest. 0.0.6 fixed the wake-up from deepsleep reason.
I Stuck now on upgrading the firmware of the LoPy on the PyTrack. Last time, I Pluged it on a ExpansionBoard. This time I soldered a switch on the LoPy. As a resut it fails allways with connection problems :-/

@crumble Hi, i have uninstall the pytrack from the device manager and plugin in again it show under "other devices" as shown below.
I followed the link in https://docs.pycom.io/chapter/pytrackpysense/installation/drivers.html although my windows is windows 8 not windows 7. But when i update the driver i encounter this showing that the third party does not contain the INF digital signature information.
How can solve this problem?
-
Please try to install the driver with administrator rights.The driver is not signed by someone whicht the OS trust. If you have the rights, you can tell the system that you trust the driver.
-
@crumble the driver from https://docs.pycom.io/chapter/pytrackpysense/installation/drivers.html is only the notepad after i downloaded it. It is not a zip file. How can i get the driver folder?
-
@mj rename pycom.inf.txt to pycom.inf . Right click and choose install.
-
@crumble The file is already an inf file. And i right click to install it still showing that INF does not contain the digital signature information.
-
@mj you still need admin rights. If you user has local admin rights, you shall be able to install it. If you computer is in a domain, you have to ask your admins. They may have restricted your local admin rights. If not try to install it as administrator. If this does not help, google "windows security settings install unsigned driver" and follow the steps for your operating system.
-
@crumble It really works for your method. Finally, it works and connected in atom. Thank you very much since i have pending this problem for weeks.

@crumble Hi, i have a doubt since i have connected my pytrack but under REPL console, it do not show the sign of ">>>" is it ok for it?
