In my case I can connect to the comport but transfer not possible even i I have DIG+ and reboot the radio. I am using a cable with profilic chip 73 de DL8LDN

phdlee commented 7 months ago

Tnx for trying this version Check if Comport is being used by another program (for example, a firmware download program, etc.). Comport can only be opened by one program. ian kd8cec

Is it the same as the previous APRS message transmission test? The frequency is entered on the APRS MSG channel, right? Everything only works on the main screen. Can't you save WSPR data? I'll test it a few times and if it doesn't work, I'll add a testable feature.

Thanks for replying, I cannot save WSPR data and transfer APRS data with UV K5 DigiManager and yes QRG is in APRS MSG channel.

mariano80 commented 7 months ago

Hi! Before several PC reboot now program works ok. But the same problem as DL8LDN. I open Port, but when I send Transfer, nothing happens on Uv-K5.

Regards and thanks for your replay!

phdlee commented 7 months ago

Thank you for testing. Among the radios I own, I found one that had the same symptoms as you. It seems that high-speed data transmission and reception is not smooth due to some additions made while upgrading from Version B to Version C. Tomorrow, based on radios with the same symptoms as yours, I will reduce the speed or eliminate anything that is causing communication problems. Please wait one day. I will update after solved.

No problem! If you need more feedback, tell me.

Regards!

phdlee commented 7 months ago

The problem seems to have been resolved. Please test. (uploaded version 0.3D) I brought the problematic laptop, UV-5K, and programming cable to a place where the problem did not occur and compared them one by one. The problem was with the USB to UART chip used in the programming cable. So it seems that the problem only occurred to people under certain conditions. So I lowered the speed to 57600 and confirmed stable transmission and reception on all cables I have.

After Installing 0.3DB, I cannot save or transfer data from PC to K5 using my programming cable and DigiManager.

phdlee commented 7 months ago

You will also need to download DigiManager again. Speed changed to 57600. Sorry for not explaining it. As the 0.3DB acceleration became 57600, DigiManager was also set to 57600 by default. Digimanager is 0.7.

Oh, I apologize, I didn't realize that the DigiManager had been updated as well.

Thank you! 73 Sean, N7SIX

Hi Ian!

Well I updated the uv-k5 fw and the Digimanager. When I connected for the first time It works great and send packet over the air. But when I try again, sometimes the app freeze or I got an exeption again. The only way to correct it is extract usb cable and close the app. Connect again and start the app.

I'l try to mmake more test to give your a better feedback. Thanks for your patience and work!

cec_0.3DB.packed.bin <-- I'm using this fw

Edit: Seems that the COM port became busy for the second time or more. The only way for Tx again is disconnecting the cable.

Regards Mariano LW2DHT

phdlee commented 7 months ago

Excellent That probably appears to be a USB cable problem with RFI Higher frequencies cause problems for computers. The test method is to press PTT while connected to a computer. You'll probably run into the same problem. There are several solutions on the Internet

  1. Do not use a USB hub and connect using a cable as short as possible.
  2. Keep the radio's antenna away from the computer.
  3. Install a core to prevent RFI in the USB cable.

Thank you now is all working like aspected 73

mariano80 commented 7 months ago

Ian! Thats correct!

In my case I used a usb 3.0 hub and works great. The problem was with the front usb port of computer.

Well If for me it is ok and for DL8DLN. I close the Issue.

Regards Ian Have a great weekend LW2DHT

mariano80 commented 7 months ago

Closed! Using a usb 3.0 hub worked for me. But the main problem is RF on Serial/USB.
