Thank you for demonstrating this. I have been thinking about this now for a while and thought that the chip must be programmable. I want to make my own homemade bluetooth speaker and give it the name of my speaker not the generic name. This is exactly what I wanted to do and now I know that these chips are not locked down but reprogrammable.
Just a thought: how feasible is it to change the embedded sounds of the BT module? Now, that would be such an interesting project 👍
different module but i saw someone who simply dumped the rom off the chip, replaced the sounds and reflashed.

@@leafpirate Thanks 👍
did you ever manage to upload a different sound for the BT activation on these chips? i recall Dariee mentioned somebody else was looking at it, but cant recall who.
Great video, however a time consuming business if you have more boomboxes ;-). Maybe you can design an adapter with pogo pins. Have seen a guy that did similar with a modified clothespin with pogopins and wires already attached to it. Saves some time and you cannot make a mistake.
I did consider making a test fixture to do it, but I only do a couple a month and I've got it down to 10 mins now!
Can I use the adruino as spi programmer?
I want to add a pairing password so my neighbors cant connect to my module. How would I go about doing this?
Sir is it possible to change the name of PCM2704 usb Sound Card like this!!!???
Does the SPI allow you to set a password for pairing? Thank you for the video.
Does the Bluetooth module have any noise or hissing when no music is playing?? It’s very common for CSR Bluetooth chips.. I’m wondering if this board has any weird noise issues?? Thanks in advanced 😊
There is a slight hiss when the device first starts up, while it's not playing anything. The hiss disappears when playback is started or after a few seconds from being switched on. For me it's really not an issue as its not noticeable unless the volume in the amplifier is way up and it's being used in a very quiet room.
Scott Marley Thank you for your prompt response! I’m wondering if a Ground loop isolator might do the trick to get rid of the hiss ...? Anyways thank you!
I have same hiss or noise problem, while integrating the Bluetooth audio receiver module (CSR57F68) with an amplifier & running from a common battery.
But when I use two batteries separately for Bluetooth & amplifier,then there is no hiss noise at all.I mean a clean sound coming .
I have checked in internet ,that it is happening due to ground loop noise.So by using a separate dc dc isolated converter the problem solves.Apart from this is there any other way to remove the noise.
Any circuit design trick i.e coupling,power supply etc.
How to activate the voice speaker of the module?
Can you show me how to change Key button?
I bought s64215 pcb only, without additional pinouts. That smallest ver. When i connected 4.2V to gnd and vbat it just heats, but no bt connection.
I got a refund but maybe i'm doing something wrong? How to enable module after connecting power to it?
Hi, I haven't used one of these boards by themselves before, however I think you might need to enable the MFB pin to enable the module. Have a look at this schematic www.electrodragon.com/w/File:CSR64215_basic_sch.png and you can see the startup delay circuit connected to MFB. If you don't want to make the delay circuit, you can probably just connect MFB to 3.3V (not VBATT!) and it might just work. I might also be completely wrong about all of this, I'm just guessing here!
I can't figure out the pins on mine. I have GND, 3.3, and 1.8 in the same place as yours. Where you have CSB, I have another GND. And across from your MOSI, I read 5v! Any idea how I can figure out the other pins?
Is it exactly the same module as this one? If not, can you point me to which one you have?
Mine have 4 pins
3.7v, GND, DP, DM
Could you please guide me on which programmer and programming software should I Use ....?
Most chips are locked down and it's very difficult to change the name. Is yours using the same chip as this? (CSR A64215). If not, I have no idea how you would go about it!
3:02 How Did You Make The Pinout Label.I cannot Find Mine On The Internet : (
I found it by googling the part number. Not every pinout is available, as manufacturers don't want consumers messing with these things!
Where i download PsTools ? Tank you

@@ScottMarley Thank you so much ! 😊
Hey man if I have a different bluetooth module how can I know where to connect the SPI? Great video btw
You'll have to look up the pinout of the particular module that you have. I've only tried it on this one I'm afraid!
@@ScottMarley ok man,thanks a lot!
Hey man, I wondering if 3V3 and 1V8 means 3.3V and 1.8V and so where do I need a 10K resistor for the 1.8V ?
Yes, that's what 3v3 and 1v8 mean. SPI_PCM is the SPI enable pin and needs to be pulled up to 1.8V for communications to work. You would probably get away without using the resistor. However, this depends on the input impedance of the pin which I dont know. To be on the safe side the 10k resistor will limit the current going into that pin.
@@ScottMarley Oh sorry I meant "why" but nevermind this answer is perfect anyway, thanks
Can i use CH341A??
I haven't tried. In principle you could probably get it to work. There are instructions here github.com/lorf/csr-spi-ftdi for using the ft232rl chip (not ch341a), but it looks like far more work than just buying a csr one from Ali Express for a few dollars so I went down that route.
