-TEMPORARY: As of this writing, the changes for the Crazyflie 2.0 target have not been merged back into the Betaflight repo -- temporarily working out of a [[https://github.com/theseankelly/betaflight/commits/cf2|private fork]]. Intent is to merge into Betaflight ASAP once a few bugs in the latest Betaflight are ironed out.

The Crazyflie can be [[projects:crazyflie2:development:dfu|booted in to DFU mode]] without needing to short this pin. Note that the Betaflight configurator will reboot the STM32 after flashing but it will not reset the NRF51 -- the whole board must be power cycled after flashing in order to restore the NRF51's Rx functionality. 
  
 Note: If you've previously installed the libusb-win32 driver on the Crazyflie 2.0 device node using Zadig in Windows, the driver must be changed before it will enumerate as a COM device after flashing.

-The defaults after flashing should be sufficient for flight.+The defaults after flashing should be sufficient for flight.

 +Some things of note: 
 +  * It's suggested to change the brushed motor PWM to something higher to reduce audible noise - 24khz works well. 
 +  * Configured to use a TARGET_CUSTOM serial Rx protocol - this is a new feature in betaflight for the crazyflie so that the NRF51 firmware does not need to change. This option was very recently added to the betaflight/cleanflight configurators, so make sure you're using the latest version of the configurators (or just don't change the serialRx protocol drop down -- it will be a blank white box on earlier configurators 
 +  * PIDs have not been tuned for the crazyflie -- the stock PIDs seem to be doing quite well though.

 To use a client that uses the legacy commander packet type (cfclient, mobile apps, older versions of DeviationTx) ensure the max roll/pitch angles are set to 50.0 degrees and the max yaw rate is set to 400deg/s. The handler for this packet type rescales the degree setpoint into a PWM-style value (range of 1000-2000) and assumes these values as max values when making the conversion. Using other values should work but might produce unexpected results. To use a client that uses the legacy commander packet type (cfclient, mobile apps, older versions of DeviationTx) ensure the max roll/pitch angles are set to 50.0 degrees and the max yaw rate is set to 400deg/s.

-Using the new CPPM Emulation commander type (supported in [[https://github.com/DeviationTX/deviation/commit/3d61a2b6c0968db2b83878c44266293386c2bc18|Deviation]]) is recommended.+Using the new CPPM Emulation commander type (supported in [[https://github.com/DeviationTX/deviation/commit/3d61a2b6c0968db2b83878c44266293386c2bc18|Deviation]]) is recommended because it allows up to 10 additional auxiliary channels.
