Application Note
1. For proper operation of LR-101H, do not leave P1 or P2 floating. Do keep P1
and P2 at fixed level; otherwise it might cause the module instable.
2. Antenna is the important part in the communication system. The quality of
antenna would directly influence the communication. Please take the antenna
type and antenna’s electrical characteristics into consideration while
integrating LR-101 into product.
