Super excited about my new 2.0 and CrazyRadio PA. I can use the iPhone app to easily connect to and fly my Crazyflie 2.0, but my CrazyRadio PA seems to be misconfigured.

I cloned the crazy-radio-firmware from git hub, made the bin and successfully updated the CRPA via my Linux machine as per http://crazyflie.blogspot.com/2013/05/c ... 0-fix.html and https://wiki.bitcraze.io/projects:crazy ... rogramming. Now when I plug it into my MacBook, the CRPA red light flashes once quickly and I see this via "system_profiler SPUSBDataType"

USB 3.0 Hi-Speed Bus:

Host Controller Location: Built-in USB
Host Controller Driver: AppleUSBXHCI
PCI Device ID: 0x9c31
PCI Revision ID: 0x0004
PCI Vendor ID: 0x8086
Bus Number: 0x0a

Crazyradio USB Dongle:

Product ID: 0x7777
Vendor ID: 0x1915 (Nordic Semiconductor ASA)
Version: 99.53
Serial Number: FFFFFFFFFF
Speed: Up to 12 Mb/sec
Manufacturer: Bitcraze
Location ID: 0x14100000 / 20
Current Available (mA): 500
Current Required (mA): 100

Should be great, right? I open the cfclient and click connect and the CRPA red light turns on briefly and when the 2.0 is on, I see the radio://0/80/250K and debug options. When I connect to the radio protocol, no lights on the CRPA or the 2.0, and then after a second, I get this in my console logs and an error dialog.

I'm gonna try to flash the firmware again, but any other ideas?

Thanks, ad

Update: After re-flashing the CRPA firmware with the pre-compiled bin from here https://github.com/bitcraze/crazyradio- ... e/releases I was able to get a connection to the copter. However, its flaky and it seems like as soon as I move the copter the connection breaks because of too many lost packets. Here's some logs. Any ideas?

Thanks.

My current best guess is that there is an incompatibility between the cfclient and the firmware in the Crazyflie 2.0. Have you updated the firmware to the latest?

After updating the firmware and using the right firmware on the CRPA, connection is stable, solid and super fun with PS3 over BT and MacBook Air. Thanks!
