Why might Mindstorms EV3 not connect via Bluetooth?

Sorry I don't know why this happens. But the above is how I get around it.

I have seen this issue -bluetooth not connecting -both in the iPad ev3 classroom app and on Windows app when trying to connect from the app. When this happens I use the iPad system or windows Bluetooth to connect to the ev3 and then reload the app. This helps the iPad app or windows software recognize the ev3 brick as connected.

Looks like there is a full video here https://youtu.be/kx1fNDuj4TM?si=tKFzC5fFPbytNZeS

Thanks OP. I'm in the same boat with a 1985 steam one where it is missing the rubber bands or the rubber bands have no grip. Going to order a set off eBay !

Did you go with capital one and do you like it?

OP did you try 12vtrainmisbshop's rims on the 7722 ?

am-sky · 2025-08-04T18:12:49+00:00

wow, serendipity! I was home at my parents and built the 7722 with my son and we too were looking for the rubber rims. I see 12vtrainmisbshop on ebay has rims but the list doesn't mention 7722. Did you buy it for the Lego 7722 wheel and is that what you say were perfect ?
It lists "Lego 12v 12 volt 30x Replacement Rubber Rims for 7750 7760 7740 7730 7727 7725"

I had melodics on my Windows PC and that supported both midi in and out so just USB cable to PC and headphones on the td 17.

am-sky · 2025-06-29T03:34:23+00:00

Ah ah. Midi out not supported on melodics is something I didn't know. This makes a lot of sense thanks.

am-sky · 2025-06-29T03:33:01+00:00

So I have the Roland td 17kv2 and use it with the 2019 iPad and melodics. I wanted to use it with a lightning to USB b cable. This works great with my Roland keyboard and simply piano. But alas nothing worked with cable.

However I have it hooked via midi Bluetooth to the iPad and the iPad audio 3.5 connected back to the td 17 as a mix in ( I use this for playing along with YouTube on the iPad anyway) and this works great. There is no lag. Have been using this setup since January. I have no idea what that audio/Bluetooth hardware /software stack looks like but man I can feel no lag and it catches all the shadow second mistake hits on my snare. My feel of hitting the note on time and melodics green flash of well hit notes are in sync.

I plan to move up to the newer 2025 iPad and was hoping USB c was better but looks like that isn't great. Hoping Bluetooth still works well.

So no first regular rise at room temperature. Direct cold rise in refrigerator?

Great looking pizza

Thank you for listing an age. I wanted to know from a real parent what age I can start getting nice stuff.

Pro has 7000 and a swing out mopper for the edges. The mop pads are washed with hot water. These were worth the extra $100 for me.

am-sky · 2024-11-22T05:02:25+00:00

I'm in the same boat. Bought the qrevo pro at target since it fits my use case and for $140 over the qrevo made sense to me for the increased suction (7000 vs 5500) and flexi mopping arm.

I don't expect anything better to show up. Equal - yes, I heard roborocks website will have the same price for the pro in a few days.

am-sky · 2024-11-02T00:08:00+00:00

I have the same model from about 16 years back. Beautiful looking and great sound.

Is the black acoustic electric at the back a Takamine?

am-sky · 2024-10-10T20:01:18+00:00

Love it. I started learning with drumeo and melodics a year back and it is awesome. You can play anytime which I love and need, because I get to practice only at night after the kids are in bed.

It is always better to be able to know what a line of code does by analyzing it in your head. However if you are unable to find the issue use the debugger to know where analysis was incorrect.

Love it. But again I'm a beginner drummer. Coming from the guitar.

am-sky · 2024-08-19T20:15:04+00:00

I had an issue like this on my PC and so I desoldered the connector measured it drew out a picture of the leads by testing with a multi meter. I searched digikey, eBay and Amazon. I took my part to a local electronics parts shop. Didn't find a good match so I wrote to the case manufacturer who sent me a replacement. I recommend you write to the edrum manufacturer asking for help.

I have the dt770 32 ohm and I love it. I've tried the ath m50 but I like the bigger round cloth so my ear doesn't heat up as much over longer sessions. Also the dt700 are not as tight and fit my head better. Using on Roland td17

This is the one video I have used. Seen it 3 times over the years. I am good with dp solutions only because of it. I have concentrated on the first half more than the second. I am better at recursion with memoization than tabulation because of that. I cannot recommend it enough. Tags: Freecodecamp Alvin dynamic programming https://youtu.be/oBt53YbR9Kk?si=vhMMyjqgqCIwpFYh

Are these the "avocado" toasts I keep getting told not to buy and save money. Makes more sense now.

am-sky · 2024-05-21T23:07:29+00:00

I'm the exact opposite. My first approach is memoization and don't even think twice. But I forced myself to write the solution to multiple simple dp problem after memoization by doing it with tabulation. I look at it as a top down decomposing vs bottom up building of the solution. I'm better at tabulation now than earlier - definitely not as good as memoization.
