CHIRP

It is either one of the following

1. you are choosing the wrong port
2. a bad connection between the programming cable's connector and the radio

If you leave the programming cable's connector unattached from the radio, the error will be the same.

A programming cable vendor had the same issue a few weeks ago. He sent me a pair of programming cables and I purchased a radio. When I received the cables and radio I tried them both out. Neither would work but my Retevis programming cable that I had for my Retevis RT6 radio worked fine. I examined that connection and it was clear that the connector did not fit the radio properly. I studied the issue and then filed on the connector as needed to allow it to fit properly and it finally began working 100%.

Thx for the help!

After some fiddling with a multi-meter and connectors I discovered the Adapter connector is the wrong type.
Based on the picture I found below the (Chinese) adapter seems to have the audio Mic / Speaker pins but not the RxD / TxD pins.

Picture also attached for the record of pin-outs.

I've ordered the official Baofeng cable now.

Arno,

Thank you for the link to the picture with the pin-outs.

Note that there are two types for Baofeng labeled programming cables with the "M" type connection.

The first type has shell that sticks out past the surface that the pins stick out of by almost the same distance as the pin do. The shell surrounds the boss on the radio that it attaches to. I found that to use this connector with my UV-9R I had to modify it in similar fashion as you described above.

The second type has a shell that is flush with the surface that the pins stick out of. This connector fit perfectly as-is. My Retevis programming cable that I received with my Retevis RT6 is like this. I recently ordered the Baofeng branded cable with the same type of "flush" connector. It should be arriving any day now. I am hoping it has the WCH CH340 USB-to-Serial chip.

I have attached pictures that show the difference between the two types.
