Do you have any sense of how much work it would take to make the Myo work without the dongle? It seems kind of silly to use it when any modern computer should already have a decent bluetooth chip.

Thalmic Labs already open-sourced the BLE protocol at https://github.com/thalmiclabs/myo-bluetooth . There are also some other projects on Github that have it working, but I didn't see one that was actually properly licensed or maintained.

I might give it a try using Bluez, but I suspect this would need to be done separately for each platform.

I'd like to add support to clear all of a certain type of handler (ex: clear_imu_handlers) and to remove the most recent one (ex: pop_imu_handler).

While I do this I could rename the add_X_handler functions to push_X_handler to better match the new pop_X_handler functions I'm adding. Do you think this is worth doing or should I preserve backwards compatibility and only add the new ones?

I've been using the myo-record script to record IMU and EMG data, at 50Hz and 200Hz (EMG Mode 3) respectively. The former appears to be functioning as I'd expected, with IMU samples recorded at approx. 20ms apart, however the latter seems to be recording a pair of EMG samples every 10ms, instead of one every 5ms.

I was hoping to seek clarification as to whether this is expected or if there is an error in my implementation.
