Hi,

Yes, I'm connected to the one that has to be soldered to the Crazyflie board.

Re: Only M2 blue led on

I have been trying to flash the NRF and after the last flash the M2 LED is flashing at a high frequency. This was the console output. bitcraze@bitcraze-vm:~/projects/crazyflie2-nrf-firmware$ make factory_reset make mass_erase make[1]: Entering directory `/home/bitcraze/projects/crazyflie2-nrf-firmwa...

Re: Only M2 blue led on

Hi again,

We finally received the ST-Link/v2 but I have no idea what I should flash. To completely reflash the NRF I just have to "make" the crazyflie2-nrf-firmware and then do "make factory_reset"?

Thanks again

Re: High frequency streaming

Hi! I have been working with Whoenig crazyflie_ros (previously I was working with cflib). Next week we should be able to do some simple position control using sound, after that I'm not sure where we are heading. We are sampling sound at 7KHz due to the restrictions in the Crazyradio PA, above this v...

Re: Only M2 blue led on

For me it has been really hard to understand to which I should be connected to, everything I read confused me more. There is the one that is already on the Crazyflie and there is the one that has to be soldered to the Crazyflie (I don't understand what is the name of each one). When running the code...

Re: Only M2 blue led on

Hi, I have been trying to flash the NRF to check if it's really fried or not, I'm using the VM and an Rlink. I've changed the interface in the crazyflie2-nrf-firmware Makefile to the rlink.cfg file and runned flash (no BLE) and this was the output: make flash BLE=0 openocd -d2 -f interface/rlink.cfg...

Re: Only M2 blue led on

I have been looking around and I noticed that the VEN_D enable which powers VCC and the STM is low ~0V. Does this still sounds like a short circuit happened or is it possible that somehow the NFR firmware got messed up? If yes the only way to reprogram it is using the debug adapter and a JTAG progra...

Re: Only M2 blue led on

Nothing gets particular warm when I plug in the battery and the battery hasn't been decharging particularly fast either. I couldn't connect to the DFU bootloader.

Only M2 blue led on

Hi again, I know this problem has been talked about here but I still wasn't able to fix it. I was flying a CF2 which I had noticed that had the power cables breaking away from the board, when I landed it and went to replace the battery both wires broke. The power wires were soldered to the board and...

Re: High frequency streaming

I believe the noise seen above is due to electromagnetic interference. After I shielded the microphone board the noise was reduced quite significantly. The crtpSendPacketISR has been working quite well but I'm now using xQueueSendToBackFromISR function. I think the bottleneck is now on the communica...
