... 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 ...
