Bluetooth DIP Module - Roving Networks
sku: WRL-08550
Description: This is a simple DIP breakout for the Roving Networks Bluetooth® module. Two 0.1" headers allow easy and quick breadboarding. All pertinent pins are broken out and labeled.The module from Roving Networks is powerful, small, and very easy to use. This Bluetooth® module is designed to replace serial cables. The Bluetooth® stack is completely encapsulated. The end user just sees serial characters being transmitted back and forth. Press the 'A' character from a terminal program on your computer and an 'A' will be pushed out the TX pin of the Bluetooth® module.
Please note: This module will be replacing the phased-out Mitsumi module. The RN-41 has a lower cost and a more robust AT command set. The shape, size, and pinout of this module is the same as the Mitsumi part, although there are extra pads on the bottom of the device for added functionality.
Do not attach this device directly to a serial port. You will need an RS232 to TTL converter circuit if you need to attach this device to a computer.Features:
- Fully qualified Bluetooth module
- FCC Certified
- Fully configurable UART
- UART Data rates up to 3Mbps
- Over air data rate of 721kbps to 2.0Mbps
- Low power sleep mode
- Compatible with all Bluetooth® products that support SPP (almost all do)
- Includes support for BCSP, DUN, LAN, GAP SDP, RFCOMM, and L2CAP protocols
- 3.3V operation
- Status pin
- Bluetooth® Technology v2.0 compatible
- Class 1 power output

If you would like to tell us more, you can fill out our form if you need some psycho-suggestive questions. Go to the form.














(conclusion: which is the maximum baud rate that is supported by the SPP, is it 3Mbps? Because the datasheet says it is maximum 300Kbps for the SPP)
Usually the COM port on PC can't go faster than 115kbps. If you want a faster interface, you must buy a specialized PCI card.
However, I purchased this module to interface it with a dsPIC, and this one : https://www.sparkfun.com/commerce/product_info.php?products_id=8180 for the PC side.
I was able to communicate between dsPIC and PC @ 921.6kbps.
But when the rate is very fast (let's say >100bytes @ 100Hz) the module stop emitting. To solve this, I was forced to configure the module in "Fast Data Mode", as explained in the datasheet.
I don't know if this belongs in the forum or out here but:
Is this what i need if i want to use a windows mobile device without a serial port as a front end for a project of mine.
I.E: Can i connect to this via bluetooth and speak to it like was it a regular serial port, or is it a bluetooth modem i am looking for?
Thanks, martin munk :)
thank you
