Re: LPS Node as Tag and Anchor

Hi Hubert, The node has an integrated tag mode. It shows up as an USB serial port so if you open the serial port with a terminal and type "t", the node switches in tag mode and starts ranging. You can press "h" to get some help about all the commands available. If you want to use a real serial port ...

Re: Too many packets lost

Yes this is right. The format is radio://<radio_dongle_id>/<channel>/<datarate>[/<address>]. radio_dongle_id allows to use more than one radio on the same system to get more bandwidth. For example radio://1/42/2M would open a link on channel 42, 2Mbit/s using a second radio.

Re: Too many packets lost

The likely cause is that you are not using the same channel in the Crazyflie configuration and in the script. Your address "radio://00/08/2M" looks a bit suspicious (the channel 08 with a leading 0), maybe you meant to use "radio://00/80/2M (channel 80)? Otherwise, the way to check the Crazyflie rad...

Re: Factory Firmware Test

Hi, The factory firmware is a lighthouse V1 only firmware and the line protocol is different, this is why you had to wait a lot for a sync: the sync is not the same. The bitstream from factory should be version 2: https://github.com/bitcraze/lighthouse-fpga/tree/V2. The tools from the git V2 tag sho...

Re: Delay in radio communication with client

FYI, I just pushed a fix for the printing problem, it was a buffer overflow when printing the message on the console. The printout is now as expected.

Re: Delay in radio communication with client

The main problem is indeed that there is a conflict between the P2P communication and the communication to the PC. This is a fundamental limitation with the current implementation and the real fix would be to have the PC part of the P2P network, in your case the easiest way to achieve that is to con...

Re: p2p -no response

It seems that you have replaced your message after I sent my last message so my answer does not make sense anymore. Can you please put back the original message and post your new question in a new message. This way this thread will continue to make sense and I will be able to answer your new questio...

Re: p2p -no response

Hi, I never looked at the console so far since I wanted to reach a working state, I just looked at the LEDs verifying the communication. It would have been useful if you could have at least verified that the M4 LED was indeed behaving the same as on my side. Anyway we seem to have reached the same p...

Re: p2p -no response

I do not understand your problems. In order to understand I would need you to follow exactly my procedure and to tell me where things starts going wrong. My idea is to start from a completely clean state and run the same steps so that we can understand what is happening. There should be no problem w...

Re: p2p -no response

Hi, You should not have to modify anything to get the P2P example to work. I tried to get it to work with 2 Crazyflies 2.1 and I got it working following this procedure: I flashed both Crazyflies using the client bootloader screen to version 2020.06. This is to make sure that everything is updated a...
