Title: Wireless (Bluetooth) for sound boards - HOW-TO!
Post by: ShtokyD on October 13, 2017, 10:26:33 AM
Wireless (Bluetooth)
for Plecter R.I.C.E. and Proffieboard/TeensySaber
sound boards
HOW-TO!

People keep asking questions about how to use Bluetooth RICE with PC RICE programm, what bluetooth module to use, what USB Bluetooth dongle to use....
I'm making all my sabers now with the Bluetooth RICE feature using a Bluetooth module, because it completely replaces the need in a RICE cable we used to, you can now adjust all your RICE enabled sound board (Crystal Focus, Petit Crouton, Prizm, Crystal Shard, Pico Crumble) settings wirelessly over Bluetooth from your PC, Android or iPhone mobile phones (I'm currently working on a single iPhone and Android app to control all Plecter Labs RICE enabled sound boards over Bluetooth.
FSC-BT909, FSC-BT630, JDY-16 modules work with iPhones because they support 4.0 BLE (Bluetooth Low Energy) technology, all Apple devices work only with Bluetooth 4.0+).

Recently I found new bluetooth modules from Feasycom manufacturer that now are my favorite. All other previous modules were not 100% perfect in terms of functionality and availability, so from now I will only recommend to use FSC-BT630 and FSC-BT909 bluetooth modules for all Plecter RICE and Proffieboard or TeensySaber builds and to use with my upcoming "ForceSync" mobile app.

So here is a small tutorial for you guys, hope there will be more sabers with this awesome feature in the community! ;)


Links for parts (FSC-BT630 and FSC-BT909 modules, +4db and +18db signal power):

BEST MODULES I USED SO FAR!

- FSC-BT630 module (only BLE): FSC-BT630 at KR-sabers (https://thesaberarmory.com/product/fsc-bt630-bluetooth-module/)
- FSC-BT909 module (Dual-Mode SPP+BLE): FSC-BT909 at KR-sabers (https://thesaberarmory.com/product/fsc-bt909-bluetooth-module/)
- can be programmed (set Name and Passcode) via bluetooth connection with official Feasycom app - FeasyBlue (search it in App Store and Google Play)

NOTE! Some TCSS R.I.C.E. cables are made with CP2102 chips, some with PL2303, and if your cable is not recognized by computer with CP2102 driver then you have to download and install an old version 3.3.2.105 (from year 2008-2009) of Prolific driver. How to do this described here: Fake PL2303 - how to install on Windows 8.1 - BartB (http://wp.brodzinski.net/hardwa…/fake-pl2303-how-to-install/)

Just curios to what particular switch is do you recommend for the Bluetooth module, since the only smd Slide switch I have come across is 50V 0.3 Amps, perhaps a link to what switch you recommend
Title: Re: Wireless (Bluetooth) for sound boards - HOW-TO!
Post by: erv on December 02, 2017, 12:00:57 AM
the BT modules uses current in the range of 40-50mA (ballpark) so your switch will be fine.

Yeah, as Erv said, these Bluetooth modules draw only up to 50mA max, so no worries about the latching switch current rating.

Updated HM-13 wiring diagram with Crystal Focus sound board, it turned out you can power the module directly from CF's on-board 3.3V regulator pad and it won't cause static speaker noise like it does on "direct drive" single cell sound boards.

You need HM-13, not HM-10. HM-10 is only BLE so won't work with your PC RICE software unless you update them all with BLE profiles support. HM-13 is "Dual Mode" - it works with EDR and BLE, automatically switches between modes if needed.

Hey @ShtokyD  !  Have you ever tried to wire both a 3.5mm jack and a HM-13 Bluetooth Module into the same lightsaber?

The thought is that if both were installed that you'd be able to either plug in the 3.5mm male or communicate to the soundboard via bluetooth from your phone/computer depending on which was available at a given time.

I have room for both in my chassis but I'm wondering if you've ever tried both, and if so are there any reasons not to do both?  Perhaps feedback, interference, etc.?

Again, room inside the hilt is not a concern.  Rendundancy is not a concern.  I'm only wondering if there would be any adverse effects from wiring in both a 3.5mm jack the conventional way and a HM-13 Bluetooth Module powered by a CEX into a Crystal Focus v8.0?

Hi, yes, I wire both in sabers where I have room like in my KAM sabers. No problems with that. You just have to use only one way to configure RICE, not try to connect both bluetooth and 3.5mm RICE cable simultaniously, but shoudn't be a problem with it either... I use a small slide switch to turn ON and OFF HM-13 bluetooth module when I want to use bluetooth RICE.

Just an FYI for everyone... I managed to tear the 3.3v pad (VCC) off of my HM-13. Totally frustrated. Then I noticed that the adjacent pad (right next to it) was listed in the HM-13 manual as NC or VCC. Turns out, I was able to wire my 3.3v directly to the pad next to the one I tore off and everything still works.

Of course, I only noticed this after I panic-ordered another 3 HM-13 boards from FastTech.

Thanks for the tutorial, BTW. Really helped me out.

Here are some links that may help others just finding this tutorial:

I didn't want to butcher my TCSS serial cable, so I got one of these from Amazon for $8: Amazon.com: DSD TECH TTL to USB Converter with CP2102 Chip Works for Windows (https://www.amazon.com/gp/product/B07B628LY8/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1)

I got my HM-13 from FastTech: .90 HM-13 Dual Mode Bluetooth 4.0 BLE SPP LE Serial Port Module - compatible (https://www.fasttech.com/product/1827700-hm-13-dual-mode-bluetooth-4-0-ble-spp-le-serial)

I finally got my HM-13 working with my CF9 and I'm having a small issue. When I click in the windows RICE app to save the config, it shuts the board down and saves all the settings, but it never reboots the board. It keeps looping through what look like a series of initialization commands but it never actually does. If I cycle power to the board manually, it boots just fine and all the settings I changed are working properly.

Ever have any issues like this or know what I'm doing wrong?

Early cf firmware has rare reboot issues after saving or isaber quit (happens only with certain SD cards which explains why we didn't catch that during development of the firmware). You can have yours updated and flashed for free, I will cover the postage of course

Thanks for the reply, Erv!

Problem is that I only noticed the problem after installing it into a saber, so I'd really prefer to not tear it apart if possible.

Can you let me know what brand of SD card you know didn't have this issue? I'd like to try getting a better one of those first.

Thanks!

thanks, I'll give it a try. I'm also inquiring for a BTLE objects for my dev env for RICE. However, I've used most of my dev time in Wifi rather than BTLE.

[addon] : obviously, it's totally possible to have a USB receiver made out of this to turn it into a univeral receiver that should work with stock RICE program (HW dependencies being pushed out of the OS). That's how my Omnisabers worked back in 2006 except that it was a MIDI device and not USB !

Yeah, try it! It works much better and faster than HM-13 or HM-17 modules. Better make a new program with BLE support and other cool features (I emailed you about it) :)

IMPORTANT UPDATE! Just tested this module installed in the aluminum hilt (didn’t think about it earlier...) and signal strength dropped dramatically unfortunately, so it still works good in up to 2 meters (depending on how thick the hilt is and how the module is placed inside, there must be no ground wires around the module antenna) area around the saber but from 2 meter and up it looses connection. But I think it still works until I find a better module.

IMPORTANT UPDATE! Just tested this module installed in the aluminum hilt (didn’t think about it earlier...) and signal strength dropped dramatically unfortunately, so it still works good in 50cm area around the saber but from 1 meter and up it looses connection... well, that only means research continues...

That's not too bad though, is it? When I'm using the HM-13, I have to remove the part of the hilt that is covering it, or I can't get it to connect at all. Is that not everyone else's experience with the HM-13?
Title: Re: Wireless (Bluetooth) for sound boards - HOW-TO!
Post by: ShtokyD on August 08, 2018, 11:21:52 AM
Usualy no, HM-13 has a more powerful antenna (+6db), so it worked fine in my sabers. JDY-16 is only 0db max. You can check if you programmed HM-13 to run at max power by AT commands.

How about putting the antenna like the old cell phones had it where you pull it out a bit when you are ready to use it? Back in the day when we only had one free hand, we'd pull out the antenna with our teeth so we could get reception (for all you young'ins who didn't know)

Better yet, 'bunny ears' from an old t.v. would get the signal no problem! And when you're playing the saber you can hunt for underground water at the same time

Well, better just use a good bluetooth module :) I'm testing HM-11 BLE 4.0 module today (same size factor as HM-13), this module has all required features and +6dbm signal power, so I really hope this one will be the one. I will let you guys know...

Well, JDY-16 still works in up to 2 meters, I just reinstalled it and moved further from ground wires and battery inside the chassis to get better antenna signal. Also a hole in the hilt will help a lot to improve the signal strength.

I'm looking through the manual at the AT commands and I don't understand which one(s) you're referring to. Which command(s) should I be looking at for the HM-13?
Title: Re: Wireless (Bluetooth) for sound boards - HOW-TO!
Post by: ShtokyD on August 12, 2018, 01:16:31 AM
All required commands are listed in my tutorial.
Update/// oh, I just noticed that datasheet says it has different power output values but gives no command to set it.... For HM-13 the signal power AT command is AT+POWE<value> (0, 1 or 2), but it doesn't work. Also set AT+MTUS1 command for higher data packet transmission and AT+HIGH1. And don't cover antenna with steel parts (steel is very bad for signal, even aluminum is better), also try to place the module far from Ground wires.
