Re: External communication not only CF Radio Dongle

Ok. First flight over LTE Cat-M1 performed :D It was a bit impossible to fly using the PS4 controller in one hand and the phone in the other, but you get the point. https://youtu.be/hDewO1xZeoI Had to adjust the Stabilizer log period to 100ms to overcome the increased latency, but flying is just nic...

Re: External communication not only CF Radio Dongle

I have made some success in my endeavour. Got the PoC LTE deck attached and communicating nicely with cflib over Cat M1 using STUN/TURN and UDP. Also got a PoC deck driver on UART2 relaying CRTP packets to and from the LTE deck. I got the get basic params example working, it reads the TOC from Crazy...

Re: External communication not only CF Radio Dongle

Yes! Quickly glanced through the Python code and it should be a fairly easy task to add a 'special' UDP driver there. Nicely packaged code, kudos! Been busy implementing a quick and dirty TURN client in C and Python so that should fit nicely. I'm thinking about how the message flow is done during co...

Re: Hover with flow deck shaking and goes crazy

I experienced the same phenomenon this weekend. It seems like the flowdeck camera really needs a well lit environment to work properly. Tried flying in the dark using Hover mode and it was impossible to get the Crazyflie stable. Altitude hold worked OK though.

Re: External communication not only CF Radio Dongle

Thanks for the very detailed input. I've followed @arnaud advice and made a copy of usblink. Initially I'm just sending the CRTP packet (as is) over the Uart2 @ 115200. Since the first byte is the actual length of the packet it makes it easier to frame it on the receiver. Simply stuff it inside a UD...

Re: External communication not only CF Radio Dongle

Hands up here as well. I'm currently experimenting with a tiny LTE Cat M1 modem. Would really appreciate any pointers on routing CTRP to one of the serialports. I have a separate STM32 handling the modem, LwIP. I was thinking of just shoving the CTRP packets into UDP and send them on their merry way...
