lily 58 nice nano: Screen/nano turns off when i turn switch on
Hey everyone! ive just finshed my lily58 build with nice nanos and nice views. I've folowed the guide and even managed to install de firmware.
When i instralled it through usb with the battery switch OFF the keyboard works! the nice view turns on and shows me the KPM and the nice nano flashes a blue light for an instant
But, the momento i turn the battery switch ON no blue light flashes on the nanos, there are no keypress responses and the view turns off (and the bluetooth pairingnalso dissapear sfrom the bluetooth device list in my mac)
what could be happening? im using a 3.7v 700 mAh battery. with reference PL 503040.
do i just nee to leave the battery charge? or is there another error?

It sounds like you've done a great job with the build so far! It's definitely strange that it works with USB but not with the battery switch on.
The battery switch needs to be on for the battery to charge, so it's possible the battery is just drained. However, a 700mAh battery is quite a bit larger than the 110mAh batteries we recommend, and it might not fit well or could potentially be causing an issue. The battery name 503040 means it's 5.0mm x 30mm x 40mm, which is larger than the 301230 (3.0mm x 12mm x 30mm) we use.
It's also possible there's a short somewhere that's causing the nice!nano to shut down when the battery is connected.
I'd recommend trying to charge the battery for a couple of hours with the switch on and see if that helps. If not, you might want to check for shorts, especially around the battery connector and the nice!nano pins.

What can i use to charge? Connect to pc? Use a phone brick connector? A laptop one?
@TyperAI What can i use to charge? Connect to pc? Use a phone brick connector? A laptop one?
You can use any standard USB-C cable and connect it to your PC, a phone charging brick, or a laptop. Just make sure the battery switch on the keyboard is turned on while it's plugged in so the nice!nano can charge the battery.
@TyperAI can you teach me how to evaluate or measure that the battery is actually receiving charge when the switch is on?
I can help with that! To check if your battery is receiving a charge, you'll need a multimeter.
1. Turn the power switch on.
2. Plug the keyboard into a USB power source (PC, phone brick, etc.).
3. Set your multimeter to measure DC voltage (usually indicated by a
V with a straight line and a dashed line above it).
4. Carefully touch the positive (red) probe of the multimeter to the B+ pin on the nice!nano and the negative (black) probe to the B- pin. These pins are located at the top corners of the nice!nano. You can find a diagram showing the nice!nano pins on the troubleshooting page of your build guide: https://docs.typeractive.xyz/build-guides/lily58-wireless/troubleshooting
You should see a voltage reading that is increasing over time, indicating that the battery is charging. If the voltage is not increasing, or if it's very low, there might be an issue with the charging circuit or the battery itself.
Be very careful not to short any pins with the multimeter probes while doing this.Troubleshooting & Pinouts | Typeractive.xyz Documentation

@TyperAI this pins B+ and B- should be empty right?
That's correct! The
B+ and B- pins on the nice!nano should be empty. You should not have header pins soldered into those two positions when installing the nice!nano onto the PCB.
The battery connects to the PCB via the JST connector, and the PCB routes the power to the nice!nano through the pads where the B+ and B- pins would normally be.

@TyperAI in the end it waS actually the batteries polarities! i changed them and it worked, but now (after leaving them charging overnight) only the right keyboard has power when turned on, not the left (when yesterday both sides were beingpowered correctly)
That's great that you figured out the polarity issue! It's definitely important to get that right.
Regarding the left side not powering on now, here are a few things to check:
1. Battery Switch: Double-check that the power switch on the left half is in the "on" position (pushed up).
2. Battery Connection: Make sure the JST connector for the battery is still securely plugged into the jack on the left PCB.
3. Battery Charge: Even though you charged overnight, it's possible the left battery didn't charge properly. Try plugging in just the left half to a power source for a bit and see if the blue LED on the nice!nano blinks when you press the reset button. This indicates it's getting power.
4. Nice!nano Seating: If you used hotswap sockets for the nice!nano, try carefully removing and re-inserting the nice!nano on the left side to ensure it's fully seated in the sockets.
5. Short Circuit: While less likely if it was working before, there could potentially be a new short somewhere on the left PCB. This is harder to diagnose without a multimeter.
If you've checked these things and the left side still isn't powering on, feel free to reply or tag me for more help.
@TyperAI i think it may be a problem with how i soldered the hotsockets into the nano, how can i resolder them while being careful no to damage the current solder nor the nano?
Okay, if you suspect the nice!nano hotswap socket solder joints, here's how you can approach resoldering them carefully:
1. Remove the nice!nano: If you haven't already, carefully pry the nice!nano out of the sockets. Try to pull it straight up to avoid bending pins. You can use a thin, blunt object to gently pry from the sides.
2. Inspect the Sockets: Look closely at the solder joints on the underside of the PCB where the hotswap sockets are soldered. Are any joints dull, bumpy, or not fully covering the pad and pin? Are there any bridges of solder connecting adjacent pins?
3. Resolder the Joints:
* Heat your soldering iron to around 270°C-300°C. Avoid higher temperatures to protect the nice!nano.
* Apply a small amount of fresh solder to your iron tip.
* Touch the iron tip to the existing solder joint, heating both the pin and the pad. The old solder should melt and flow smoothly.
* If needed, add a tiny bit more solder to create a nice, shiny, cone-shaped joint that covers both the pin and the pad.
* Repeat for any joints that look questionable.
4. Check for Shorts: After resoldering, it's a good idea to check for shorts again with a multimeter in continuity mode, especially if you saw any bridges before. Make sure the keyboard is powered off.
5. Re-insert the nice!nano: Once you're confident in the solder joints and there are no shorts, carefully re-insert the nice!nano into the sockets. Ensure it's face down and all pins are aligned before pushing it firmly into place.
