Description
The RN-41-SM / RN-42-SM is a though hole, low
power and highly flexible Bluetooth socket module .
This module supports SPP/DUN and HCI Bluetooth
interface protocols, is simple to design in and fully
certified. With its high performance on chip antenna
and support for Bluetooth® Enhanced Data Rate
(EDR), the RN-41 / RN-42 delivers up to 3 Mbps data
rate for distances to 100M / 20M. The RN-41/RN-42
socket module is the perfect method for adding
Bluetooth wireless capability to existing products
without redesign, saving you significant time and
money.

... Design Concerns 1. Reset circuit. RN-41-SM / RN-42-SM contains a 1k pullup to VCC, the polarity of reset on the RN-41 / RN-42 is ACTIVE LOW. A power on reset circuit with delay is OPTIONAL on the reset pin of the module. It should only be required if the input power supply has a very slow ramp, or tends to bounce or have instability on power up. Use microcontroller GPIO to control reset once power is stable ...
