Description: This 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.

Note: These modules have been revised to remove three unused RF pads from the bottom of the module. For more information on what pads were removed and why, check out the change notes below.

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

Customer Comments

  • What do all the **** mean?

    • Nothing, it was just a formatting error from when we moved over to a different back-end system. All fixed now! :)

  • Does anyone know if this (or the previous version) can be used to make a Bluetooth HID keyboard without excessive difficulty? The datasheet and Microchip’s website show that you can order this device with a version of the firmware that supports the HID profile, but the firmware is not available to download (despite the datasheet implying it’s upgradeable). The “HCI Mode” section of the datasheet says it’s possible to use this device as a plain Bluetooth modem with an external microcontroller, which could be the only way to do it. However, it doesn’t say how to put the device into HCI Mode.

  • Can I use this with an arduino to control io with my iphone?

    • Apple classic bluetooth is encrypted, so you would also need an authentication chip. The RN-41-APL version has this chip installed, but you need to be MFI certified to order it. To get MFI certification, you need to do a lot of paper work and jump through a lot of hoops. My advice: use bluetooth low energy (Smart Bluetooth). This works on both Apple and Android (4.3 or later).

Got the job done

Decent range, our lab is ~ 50ftx80ft with LOTS of interference/bookshelves etc. and this works smoothly anywhere within and even to some extent outside the front door. communicating between a dsPIC33ep and a desktop at 921k baud works great with low latency. I bought 2 more after evaluating the first one.


Easy to use

Works great with every terminal I have tried. Very easy ti use. Make sure it is bypassed well though, relatively high current on TX.
