Cyberbrick Cores not connecting to Cyberbrick MacOS app

Hi guys, im on wits end with this…

All 4 of my cyberbrick cores arent connecting to the cyberbrick macos app through bluetooth or even a cable. Is this a software issue or a hardware issue.

Also the light is green on the esp32 and white on the core board.

The CyberBrick remotes are the ones that connect first; you can put the receivers to one side for testing.

Are you able to connect using the mobile apps?

If so, you may need to enable Bluetooth discoverability on your macOS or enable any permission requirements.

If this also fails, then the following is unlikely, but worth ruling out.

There have been two versions of the receiver/transmitters; the originals were WiFi, and the new ones are Bluetooth.

It is important to note that the WiFi ones should have only been sent out to reviewers (like me). They also had handwritten numbers on stickers, which may have been only on some boards, though.

So, this test is purely to rule things out.

To rule this unlikely situation out:

  1. Use your mobile phone
  2. Navigate to the WiFi section
  3. Locate the pairing page (this is where you see a list of available WiFi transmitters).
  4. Turn on the Transmitter on your CyberBrick.
  5. Do you see a new entry appearing in the WiFi list?

I can connect the boards to the cyberbrick app on my phone.
However, when I look at the wifi networks, I see the ESP network.
Very interesting…

If you have it working on your phone, you have the correct boards.

It sounds likely that an issue with connectivity to macOS which needs investigating.

I also have the ESP entry, the boards can use WiFi if you program them (not using the apps to connect things), and they are based on ESP chips.

I hope its just a v1 software problem. Ill try on my dads mac tomorrow and see if it still doesnt work.

Hey,
Quick question… what does your core show up as when you search for it over Bluetooth? Is it named BBL_Shutter or RC_module?

Also, just a heads-up: make sure your phone and computer aren’t both trying to connect to it at the same time. It can cause issues, so try turning off Bluetooth on your phone or removing the device from the paired list before you connect with your computer.

Might help you

It shows up as RC_module.
I did not have the app downloaded on my phone when i tried to connect on my laptop though.

Is the BT version of your mac 4.2 or higher?
Do other BT devices work for normally for you?

Other BT devices work fine.
My macbook air M1 has bluetooth 5.0

Ok, looks like macOS was restricting bluetooth access. access to the app… even though I enabled Bluetooth. Now it works! Thanks!

So this then?

From your first answer.

Yes, but the permissions are not under the Bluetooth menu, they are hidden in Privacy.

I never said they were. They are not hidden; that is where they are located.

The word or separates two different things.

Bluetooth discoverability is one thing, permission requirements are another.

This is why we use the word ‘or’ in sentences.

I suggested you try the mobile apps, which you hadn’t, and they did work when you tried them.

Assuming that was the case, you were to check the Bluetooth discoverability (which you said showed them).

I again pointed out it was a connectivity issue with macOS, which needed to be investigated.

It turned out it was the permissions suggestion.

Restricting, you say, that is another word for permissions, right?

Amazing, you stated a problem, I gave the answer, the solution was that answer, yet weirdly, you arrived at the stated solution without any assistance.

Sorry about that. Next time i will do better.
