Description: This is the non-HID RN-42 module from Roving Networks, a 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.

The RN-42 is pin a compatible substitution for the RN-41. The primary difference between the RN-42 and RN-41 is that the RN-42 is a Class 2 device meaning its range is about 50 to 60 feet and correspondingly the power consumption is reduced.

The RN-42 is perfect for short range, battery powered applications.  The RN-42 uses only 26uA in sleep mode while still being discoverable and connectable.  Multiple user configurable power modes allow the user to dial in the lowest power profile for a given application.

Supporting multiple Bluetooth profiles such as SPP and HID and simple UART hardware interface, it is simple to integrate into an embedded system or simply connect to an existing device.  The RN-42 is FCC and Bluetooth SIG certified making it a complete embedded Bluetooth solution.

Features:

  • Fully qualified Bluetooth module

  • Fully configurable UART
  • UART Data rates up to 3Mbps
  • Over air data rate of 721kbps to 2.0Mbps
  • Low power sleep mode

  • I bought this module and can’t seem to get into command mode. I have tried every thing i can think of including: using a uC(atmega), connecting through Bluetooth(XP,Win7,android), and USB rs232 to TTL. Nothing seems to work. The module seems to just stay in SPP mode. I have probed the data to and from the device where possible with a logic analyzer to double check the baud rates and data. Does anyone have any similar issues with this module or could offer some suggestions? Model: RN-42 IC: 6514A-RN42 HID651

  • Confused- it’s non-HID and supports HID at the same time? Or bad copy/paste?

    • This is the non-HID firmware loaded version. I.e. This is the serial wire replacement. It can still be loaded with the HID firmware at a later date using the SPI interface.

      • Actually, since this includes the v6.15 firmware, you don’t need to re-flash the module to switch between HID and SPP. It can now be done using AT commands as follows:

        S~,6    // Enable HID on reboot
        R,1     // Reboot
        S~,0    // Enable SPP on reboot
        R,1     // Reboot
        
      • Ahhh, got it. Thanks!
