The RN41XV and RN42XV are small form factor, low-
power Bluetooth radio modules offering plug-in com-
patibility for the widely used 2 x 10 (2-mm) socket typi-
cally used by 802.15.4 radio modules.
• Bluetooth
SIG certified
• Certifications:
FCC, IC, CE
Based on the popular 2 x 10 (2-mm) socket footprint
often found in embedded applications, the Roving Net-
works’ RN41XV and RN42XV modules provide Blue-
tooth connectivity in legacy and existing designs that
may have been based upon the 802.15.4 standard.
• Environmentally
friendly, RoHS compliant
Applications:
• Bluetooth
replacement for 802.15.4 modules
• Cable
replacement
The RN41XV Class 1 Bluetooth module is based on the
RN41, and the RN42XV Class 2 Bluetooth module is
based on the RN42. These modules are simple to
design in and are fully certified, making them a com-
plete embedded Bluetooth solution. The RN42 is func-
tionally compatible with the RN41.
• Barcode
scanners/readers
• Measurement
and monitoring systems
• Industrial
sensors and controls
• Medical
devices
• Computer
accessories
The Class 1 RN41 module has a range up to
100 meters. The Class 2 RN42 module has a range up
to 20 meters.

DESIGN CONCERNS
The following sections provide information on design-
ing with the RN41XV and RN42XV module, including
radio interference, factory reset, connection status, etc.
4.3
Factory Reset Using GPIO4
Roving Networks recommends that designers connect
GPIO4 (pin 8) to a switch, jumper, or resistor so it can
be accessed. This pin can be used to reset the module
to its factory default settings, which is critical in situa-
tions where the module has been misconfigured.
T
o
reset the module to the factory defaults, GPIO4 should
be high on power-up and then toggle low, high, low,
high with a 1 second wait between the transitions.
4.1
Powering the Module
Apply ONLY 3.3 V ±10% regulated power to pin 1
(VDD) and pin 10 (ground). The module does not have
an on-board voltage regulator and MUST be powered
from a regulated 3.3 V power supply.
4.2
Reset Circuit
The RN41XV and RN42XV modules contain a 1k
Ω
pul-
lup to VCC, and the reset polarity is active low. The
module’s reset pin has an optional power-on-reset cir-
cuit with a delay, which should only be required if the
input power supply has a very slow ramp or tends to
bounce or have instability on power up. Often a micro-
controller or embedded CPU I/O is available to gener-
4.4
Connection Status
The RN41XV and RN42XV modules have an on-board
green LED to indicate the connection status. The con-
nection status LED is located in the lower right corner
of the module.
