Other Parts Discussed in Thread: MMWAVE-DFP
Tool/software:
I think it will be better if I go straight to the point. I'm facing a peculiar issue in the parameter configuration for the MMWAVE-DFP example executable. I'm trying to use this tool to enable myself to capture and parse ADC data without mmWave Studio, which turns out to give me some problems I didn't expect at all.
Following other issues on the forum, I managed to understand how to enable multiple TX antennas on my radar device, using multiple chirps from the same profile, and using a frame that uses chirps from start index 0 to index 1 - having 2 different chirps, that transmit from different antennas, the device is actively transmitting and receiving chirps from different TX antennas. The files are correct, the size is correct, everything seems to work. The problem arises when I try to enable 3 TX antennas using the same technique: the executable has no problems, the setup is performed without issues, but when it's time for the data capture to start it stalls, until it gives me the following error:
Sensor Start failed with error code -8
Looking at what every error output code is meant to be from the mmwavelink.h file, -8 should be related to some kind of timeout (the device is expecting something to start, probably the TX antennas themselves, but nothing happens and it gives up on waiting); after the error is logged from the program through the terminal, the program finishes running "with success", but when I look into the /mnt/ssd folder, no file is created under the folder that should contain captured data.
And it's even more strange when I try to setup 2 chirps, but with different start/end indexes, because it gives me the exact same error even though the use of 2 chirps was working fine just some minutes ago. I simply don't get what is causing problems, and this whole situation makes me even less clear how the radar works, because this almost surely implies that some other kind of parameter is conflicting between the use of multiple antennas, I don't know what it is and how to change it, and it's probably something out of my control entirely.
I'm really looking forward to help, thank you in advice.
