Re: Crazyflie 2.0 Power Output?

I do not understand if you are after the radio or power supply power so I can answer both :). Crazyflie 2.0 has a radio power amplifier that can output up to 20dBm/100mW on 2.4GHz. If what you are asking for is the electrical power supply, you can get regulated 3V on VCC for up to 100mA and unregula...

Re: TWR-TDMA problem

Hi Carlos, this sounds like a bug that could happen in case two copters have their timeslots colliding and the twr code not handling it properly. Are you sure you are not having other CF2s or anchor in TDoA3 mode talking in the neighborhood? One things you might try is to update the dw1000 lib in th...

Re: Understand the firmware of CF2 and modify accordingly

Passed the intro, the next step for the firmware documentation is the code itself. Maybe you can tell us a bit more about what you are trying to achieve and we could point you in the right direction. Our latest blog post actually discuss a bit the process we had to setup the IROS2018 demo: https://w...

Re: CRTP - Message Contents Question

Hi Jess, Unfortunately the wiki is not complete for this. The next best reference is the python lib and the Crazyflie firmware . 1. The format is: <port/id>, <CREATE_BLOCK>, <block_ID>, <variable0_id>, <variable1_id>, ... This adds a block block_id with a list of variables. The block_id is whatever ...

Re: 4 crazyflies 2 crazyradio LPS with ROS

Hi,
Unfortunately I do not have any more ideas other than the checksum error message should definitely not happen in a well configured and compiled ros workspace. You could try to post a ticket on the crazyflie_ros git repos, they might have an idea of what could be happening.

Re: orginal PA dongle firmware with USB bootloader

If writing the firmware does not work, writing the firmware and the bootloader will not work. I have never managed to get the buspirate to work properly to flash the Crazyradio and I have never liked this script very much because it erases everything instead of erasing only the firmware, I added a w...
