page 20 of 25 19. Design notes 1. Some power rails have to be externally connected, see section-11. 2. The BT RF signal has two routes to the antenna. The 1st route goes to the PCB trace antenna through L1, The 2nd route goes to pin-2 on the module through the R1 resistor then to the external antenna, the R1 resistor is not populated as default. Using the external antenna gives better performance and a longer RF signal range.
