Recently got a BTech GMRS V1. Connected to it with a known-good FTDI cable and was able to download and save the initial setup, per the CHIRP recommendations. I added a few local freqs and successfully uploaded to the radio. All good.
A few days later, I attempted to make a few changes to a GMRS repeater setting. When I attempted to upload to the radio (with the same previously successful cable), I got the message "Error reading data from radio: not the amount of data we want." Same result attempting to download.
A search for this issue with the GMRS V1 on the wiki attributed the issue to a cable problem, but this cable has been used successfully with this radio, as well as several other Baofeng and BTech radios.
Using a MacBook, OSX 10.7.5, CHIRP daily-20180606.
I understand the GMRS V1 driver is in beta. Just just thought you ought to know.

I am using the btech PC03 FTDI cable and still getting the issue listed above.

I am not sure about the mac, but on Ubuntu, I got that message when I had the wrong USB port selected on upload/download. For Ubuntu, I selected /dev/ttyUSB0 instead of the default per some recommendations I found via searches. It's possible that a similar change might work on the mac, but I'm not sure what the correct port would be for mac. I too was connected to a BTECH GMRS V1, but I have other radios as well and I select the same port for them as well -- which makes sense since this is really a host setting for which port the program should use to get to the device.
