Particle community,
Hoping to get some support in regards to the cellular modem for Tachyon.
I am running ubuntu 20.04 -> Particle Linux 1.0.18
I have a working FloLive eSIM profile. However, when I go to transfer (upload) a ~50MB file to an AWS S3 bucket, I see the upload speed drastically throttle back in the 100-300kbps. For the first 3 seconds it transfers at 2-3Mbps.
I then switched to my WiFi connection and saw basically the same thing. I did find a setting to change the power save mode to disabled for the WiFi radio. The transfer worked great after that.
I tested the ethernet connection and it never had any issues.
FloLive ensures me that I shouldn't be seeing this issue. At first, I didn't agree, but once I saw similar results with WiFi and the fix was a power issue, it makes me think that the Tachyon is throttling back in order to save on power.
Is there a way to change the power settings for the Cellular Modem? Any other root cause thoughts? Things I can test?
Anyways, thanks for your time. This thing is bad to the bone. Can't wait for the all the kinks to get worked out with the new linux build.
Please see attached photo... I currently have both CSI lanes running with dual 16mp cameras. One of which has a 25mm lens installed. Pimoroni NVMe 1TB SSD. USB3.1 all the way to a IP67 connector so I can plug into a dock when I need desktop access. External Button for powering the device. I was originally wanting to use the M1 enclosure but there was no good way to get a USB3.1 cable out the the M20 interfaces. The provided right angle ribbon USB is not 3.1. Anyways, super cool SBC.
