https://github.com/mholling/rpirtscts Being able to connect the M100 directly to the Raspi and not have to mess with USB is very compelling :) Tom Hoppe On Tue, Dec 22, 2015 at 11:21 AM, Tom Hoppe <[email protected]> wrote: > I had an idea of directly connecting to the M100 over BT, but it sounds > like it may not work with no hardware flow control...I recently purchased a > Bluetooth 4.0 Console Adapter for Raspberry Pi (see > http://www.mindsensors.com/rpi/75-bluetooth-40-console- > adapter-for-raspberry-pi) and it works great for its intended use.
