Can I connect my phone and my friends phone, and either of us can play music? Not at the same time, of course. But will it support multiple connections?</p>

(The pins on this module are <em>very</em> small and close together.) We have the same module on a <a href="https://www.sparkfun.com/products/11927" rel="nofollow">breakout board</a> that might be easier for you to use.</p>

I threw it into a senior design project for a portable headphone amplifier and it really works great. It retrieves meta-data for any media that is playing if you connect it to a phone and the audio quality is excellent! This price is also very comparable to the Digi-Key price. I would absolutely buy the Sparkfun jamboree for testing debugging before you embed this into a project. I love all the options this device offers! Thank you Sparkfun.</p>

If not, could SparkFun make one? I know there is one for the breakout, but it would be helpful to have just the SMD available in fritzing to create a custom pcb.</p>

AKA I need bidirectional audio support between 2 modules. I want to connect a off the shelf headset with boom mic to one module. The other to connect to mic input and mono audio out on a amateur radio. could these modules handle this? The ability to send a Push to talk sig from head set to radio would be a big plus as well.<p>Charles, KC3ANJ</p></p>

I intend to use the I2S out from BC127 from the to connect to a separate hifi DAC of my choice. Can I access I2S do this directly without further configuration of the module? I would like to stream audio from my iphone to the remote DAC.</p>

A soldering oven maybe? but would a regular convection toaster oven work? lol...</p>

You should check out the SMD soldering tutorials too, you might be able to blob on a bunch of solder and then wick it off with solder wick.</p>

Pins are way too tight... anyone got any advice?</p>

Both a 3.3V and 5V Pro Mini are used in the hookup guide. The supply voltage in the BC127 datasheet is listed as 3.3V to 4.7V, so 5V should be fine, right? I wanted to ask because the RN-52 Bluetooth module that is also sold on a breakout board by Sparkfun is very specifically only a 3.3V chip, so I don't know how strict that is with this one.</p>

I want to know, what is the minimal setup for the chip to broadcast a signal to a phone.<p>If I connect VDD_PADS, VBAT to a 3.7V battery, should I use VREGEN, VCHG, VBAT_SENSE?
Can I connect VDD_PADS directly to a battery, or do I need a 3.3V regulator?</p><p>The schematic posted in the comments is for a much more complex setup than I want and I don't think I need to tie all of those pins to power, do I?</p></p>

See this schematic for details https://www.bluecreation.com/userfiles/BC127%20Discovery%20Board%20v2_No%20Co%20Pro(1).pdf<p>It also helps to tie reset pin high with a 10 kOhm resistor.</p></p>

I have the breakout board and it works great. From what I can tell, for bare bones operation, all I need to connect is:<p>PIN 1 (Ground) -> Gnd<br>
PIN 34 (3V3_USB) -> 3.3 V regulated power supply<br>
PIN 41 (UART_TX) -> MCU RX<br>
PIN 42 (UART_RX) -> MCU TX</p><p>Is there any other logic required? I can't get it to cycle on.</p></p>

See <a href="https://learn.sparkfun.com/tutorials/understanding-the-bc127-bluetooth-module/usage-examples" rel="nofollow">this examples page</a>, the module has SPP support.</p>
