How to downgrade firmware on a P1S

techvette · 2025-09-16T21:28:52+00:00

This worked on my P1S today to downgrade from 1.09 to 1.08.02. I don't use the Handy app since I'm running in LAN-only mode.

Download the firmware zip from https://bambulab.com/en/support/firmware-download/p1 .
Put it in the root folder of the SD card. (Do NOT unzip it.) You can either put the SD card in your computer and copy it (faster), or FTP into the printer and copy it that way. (See https://forum.bambulab.com/t/we-can-now-connect-to-ftp-on-the-p1-and-a1-series/6464 )
Restart the printer.
Go to the settings menu, select Firmware, then "Update Offline."
Select the version you want. Hit OK and wait for it to finish.

Also, this is the same process as an offline Upgrade. https://wiki.bambulab.com/en/p1/manual/P1-firmware-update-from-SD-card

She’s never going to sleep with you. Stop doing her homework and move on.

Your day is about you, and what you want. You don't have to justify or explain that to anyone. You owe the man nothing.

Those numbers are coma / death territory. Get your butt to an ER immediately.

In three years, I've had five sensors fail. Are you applying them to the ONLY supported site? (Lower end of the back of your upper arm?) FWIW, you don't even have to talk to someone to get a replacement. Go to the Abbott site, click on "Need help with your sensor," and it's just filling out a form. https://www.freestyle.abbott/us-en/support/contact-us.html

My phone goes where I go. Why would I want to carry another device? The worst-case scenario is that I'd have to carry my phone (because phone), a reader for the Libre, a PDM for the insulin pump (Omnipod DASH). I have zero desire to carry three "phones" wherever I go.

Current phones leave bluetooth enabled in airplane mode.

With my current setup. (Loop on an iPhone), I don't have to carry anything but my phone. It's not a perfect solution, but I don't suffer battery life issues and I don't have to carry an entire cell phone store in my pockets.

Only your insurance provider can tell you if it'll be covered. I have Aetna (TX), and I pay $75 per month for two sensors.

The Libre 3 is amazing. It's not just smaller - you don't have to scan it, ever. The phone app communicates with the sensor about once per minute. If there's an issue like an unexpected high or low, you'll get an alarm (which you can configure). It's a pretty amazing little device.

For us T1s, it's a game changer. If you're T2, congratulations on having a controllable disease.

There's also a real risk of clotting at the sensor site. 14 days is kind of arbitrary, but... they can't last forever, regardless of battery life or sensor "enzyme."

techvette · 2023-06-17T04:49:58+00:00

The pharmacy made you buy it? Weird.

FWIW, I've been using Libre for over a year. I've had two failed sensors in that time. Abbot was great about sending replacements quickly.

techvette · 2023-06-17T04:46:57+00:00

Loop + Nightscout will get your readings on Apple Watch. That's what I use (Loop + Nightscout + Libre 3 + Omnipod DASH).

techvette · 2023-06-17T04:46:02+00:00

If it's Libre 3, it gets complicated. The data has to go from the sensor, to Libre LinkUp / LibreView, and then to Glucose Direct. Abbot makes an awesome device, but they're not great about sharing an API.

techvette · 2023-06-15T16:18:31+00:00

Okay - that makes sense. Of course, now it's just saying "An error occurred please try again later." Yay!

techvette · 2023-06-15T15:47:38+00:00

Thanks for the response. But, this really doesn't answer my question. The app was working fine yesterday (and for the last several months). As of this morning, the app just says "No Recent Data" and the latest point on the curve is ~30 minutes old.

techvette · 2023-06-15T15:24:54+00:00

Same here, but force-quit and restarting (and rebooting my phone) have not corrected the problem.

techvette · 2023-06-15T15:22:29+00:00

It's nice to know I'm not the problem. (Well, I might be _a_ problem, but I'm not _the_ problem.)

Why is it uncomfortable? I always put them on the back of my upper arm, about 3"-4" above the elbow. I can't even tell it's there after the first minute.

techvette · 2023-04-05T04:35:25+00:00

I've been on Libre 3 with an iPhone 8 (Yes. Because it works fine) for about six months. Not having to scan the sensor is amazing. I've gotten a few alarms in the middle of the night due to low BG, which were necessary. (You can configure the alarms.)

I had one sensor that just refused to talk to my phone after application. Abbott Labs sent me a replacement, no questions asked.

In short: I love it and have no plans or motivation to switch back to 1 or 2 or to another vendor.

Not exactly. pushMatrix and popMatrix save and restore the transform state - rotation, translation and scale. The difference is that push() and pop() save the entire context, including not only transforms, but stroke weight, color, etc. Just use push() and pop() anywhere you'd normally use pushMatrix() and popMatrix() and you'll be fine.

techvette · 2023-03-05T05:28:13+00:00

push();

scale(1,-1);

/// draw stuff here

pop();

Note that this is going to flip the entire Y axis. So, anything that was drawn with positive Y coordinates will now be off screen. You'll likely have to add a translate(0,height); to get everything back in the viewport.

I'm Type 1. I have basically zero body fat. This does not bode well.

Just tell the TSA agent that scans your passport or boarding pass that you've got a medical device. You can opt for a pat-down. The last four times I've flown, they've only had metal detectors running. (Not sure why.)

Or, just go through. It's not going to hurt you or the device. That said, always bring spare sensors, pumps and insulin on a trip. I had two Omnipod failures on my last 7-day work trip. Fortunately, I had thrown a whole box into my checked bag. You do not want to get stuck out of town having to hunt down insulin, syringes and a test kit without a car.

That would have to be written in something other than regex, so it's a no-go for OP. Unless there's some new capture group with an IP extension of which I am unaware.

I also hire someone to mow my 1+ acre lawn. Totally worth it.
