Antenna
Antenna type
PT825XXBTV2 uses an onboard PCB antenna with a gain of 2.5 dBi.
For optimal RF performance, it is advisable to keep the antenna at a minimum distance of 15 mm from other metal components. Presence of metal objects in close proximity to the antenna may significantly diminish wireless signal strength, ultimately impacting the RF performance. Therefore, when creating a final product, sufficient space must be allocated for the antenna.
