The custom personality chip demonstrated in my first video was quickly put together without much understanding of how the audio is organized and utilized. That information would come with further research, including simulating Bluetooth beacons and observing how the droid reacts.
For an in-depth explanation about Bluetooth beacons and droids see this excellent video:

Unfortunately my droid broke soon after that first video went up and it's taken me a couple weeks to bring it back to life. It lives again; a defender of the night. Now to continue my research.
You can follow along as well. Information I'm mostly confident is correct I add to my shared Google spreadsheet:

That is really amazing. I don't know why I'm getting starwars recommendations but this is really something.

@Lasiro104 5 лет назад

Keep up the awesome work! I would love to do some mods to my BB unit when the methods become more robust!

Great work! I just picked up my first droid a few days ago. Are you thinking about posting your methods for extracting the code (or the code itself)? Or the contents of the personality module SPI flash?

@Ruthsarian 5 лет назад

I won't be posting the contents of the stock personality chips and the droid code. I worry there would be potential legal ramifications. I might do a video on how to access the personality chips' content and the droid code, but I'm not sure how useful it'd be. Here are some references for those who want to try. This page documents the flaw in the nRF58122 that allows reading of the chip's flash even if read protection is enabled: blog.includesecurity.com/2015/11/NordicSemi-ARM-SoC-Firmware-dumping-technique.html Here's a rig that uses a CH341A (US$10-15 on Amazon) to read personality chips: imgur.com/a/eA9zgyJ

@thomasvickers 5 лет назад

@@Ruthsarian thanks for that info. I understand about not posting the code. I have some SPI flash chips and a programmer. I might try writing my own. If you decide to sell some of your PCBs, let me know.

Grate videos. Love them all. Think maybe the potentiometer is related to sensing the upright position of the bb8?

@Ruthsarian 2 года назад

i think the pot is for adjusting power to the wheel so the BB drives straight.

@cubegaming2300 4 года назад

Thank you I think I'll make a master chip 🤣 now I just need to program a blue tooth transmitter with all the beacons to selectively broadcast. That being said maybe the second blue led is for Bluetooth handshakes. Looking for improvements to my BB the side wheels look like the should be bearings and not wheels the one currently installed is causing unecessary vibration. But in a better motor and replace the magnets for the head and I bet my BBe will be running like new.

@AbuMaia01 3 месяца назад

When you were replacing the bluetooth module chip and copying the programming across, did you see where the stock droid affiliation is stored? Is it possible to alter a droid's affiliation without using a personality chip?

@Ruthsarian 3 месяца назад

not really, no. the affiliation is part of the personality chip. if you don't have a personality chip installed then the personality chip that's stored in the rom of the audio controller is used. the audio controller chip is different from the bluetooth chip. i haven't been able to access its contents. i suppose it might be possible to patch the firmware of the bluetooth chip to use a fixed value for affiliation rather than querying the personality chip, but that gets into ARM assembly and I'm not well versed in that type of stuff.

Is this the only way to put custom sounds? I'm trying to find a modding community for these droids

@Ruthsarian 4 года назад

it's the only way to put custom sounds on an otherwise stock droid. check out the galaxy's edge discord server. there's a channel dedicated just to droids where people share their mods. swgediscord.com

@thespencerowen 4 года назад

I'd love to know how it works.

@Lucas-Stl 4 года назад

I’m surprised you haven’t started selling custom chips, too difficult maybe? I know there are a Lot of Droid builders out there that come up with crazy ideas. To be honest though, I’m not much different with my idea to take an R3 unit and make it like Analyzer from Star Blazers.

@Ruthsarian 4 года назад

i've thought about it. i've sold a few to test the waters. the biggest issue is that people usually want copyrighted material (clips from TV shows or movies) and I don't want to risk the wrath of copyright lawyers. if i were to sell them i'd need to have something copyright free to offer; i'd need to craft another 5 or so custom personalities so people would have some variety to pick from. i haven't done that yet. but i am working on it.

@Lucas-Stl 4 года назад

Ruthsarian *noding* I hear ya. . . . You could sell blanks, letting the buyer add their own choice. Far as I know, copyright doesn’t apply if one makes for themselves...

@h0udinl 5 лет назад

Can you sell them and make a program to program them

@wesclinton7825 Год назад

How did it all turn out?

@willraya1791 2 года назад

how dose the droid know when it is being powered up for the first time and is there a way to activate it like that

@Ruthsarian 2 года назад

yes, do a factory reset and then pair the remote and droid like normal and you will hear the droid play the activation noise it makes only when first activated at droid depot. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gKocbzvLSUg.html

@thehambonetelevision 4 года назад

i wanna buy one plz

@Ruthsarian 4 года назад

the issue with selling personality chips is i would only be able to sell chips with personalities that i've designed using my own audio. i couldn't use any copyrighted material such as audio clips from movies or TV shows. i've created one "personality" so far and were I to start selling them I'd want to have a library of at least 5 or 6 for people to pick from.

@thehambonetelevision 4 года назад

@@Ruthsarian what if it came blank and there was like a dock for the chip that plugs into ur computer and alows you to drag and drop files

@Ruthsarian 4 года назад

@@thehambonetelevision that would require development of custom hardware (to plug the chip into) and software (to encode and write the audio clips to the chip). i don't think it'd be worth the effort. it'd be easier (and cheaper) to program the chip the regular way. if you haven't already, see this playlist of videos showing how to do all this using existing hardware you can buy off amazon and software that you can download for free: ru-vid.com/group/PL1LWtA1iy9htxbn6YRiQPNZSwZlszt2Kj

Can you do this with an iPhone?

@Ruthsarian 5 лет назад

yes, there is an iOS version of the nRF Connect app I'm using in this video. -- EDIT BELOW -- I'm completely wrong. The iOS version of nRF Connect does NOT allow creating custom beacons. it appears this is an intentional limitation of iOS; custom beacons are not possible on iOS devices.

@davisbenecke3623 5 лет назад

Well I have since found out you can’t do this with the IOS app because it doesn’t let you make custom signals. Thanks though.

@Ruthsarian 5 лет назад

@@davisbenecke3623 You're right. I'm sorry. I had assumed they would have the same functionality across platforms, but they do not.
