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
2. Factory reset PIO4. Connect this pin to a switch, or jumper, or resistor for access. Can be used to reset the
3. Connection status. PIO2 is an output which directly reflects the connection state, it goes HIGH when
4. HCI mode. The RN41-SM module must be loaded with special firmware to run in HCI mode. When in HCI mode
5. Shutdown mode. Pin 9 Shutdown has a pullup to 3.3V. If you pull this pin LOW it shuts down the on board
