Description

I have 2 BF-888S that won't enter programming mode. It seems like there is an unexpected character on the serial before the CMD_ACK character. If an extra character is read and discarded from the serial before we read the ACK it works.

Modified h777.py and log running it attached. Not sure if this is an issue with my programming cable but it works with a Baofen UV-B5 without any similar modification.

Daniel,

I just help someone else with a BF-888S that kept getting "Radio refused to enter programming mode". The solution was to tune the radio to channel 16. Can you verify this?

  1. can you try with latest daily and attach a debug log?
  2. can you try with a "fresh" plug-in of the usb transfer cable, to ensure there are not extra bytes laying around on the serial buffers. (i.e., remove your usb transfer cable, and plug it back in before attempting a download or upload)?

Hi Jim and Jens, putting the radio on Ch 16 does help! I think you can safely close the issue.
