BLE Module Placement Tips 1) To enable DTM mode for R/F Test like BLE fix frequency Test, FCC test…etc., RXD and TXD pad require to connect to RF Equipment though RS232. RXD and TXD pad located on the back side of the module. Reserve hole at Main PCB for soldering RXD & TXD pads for RF Equipment . 2) Module Soldering on Main PCB, ensure antenna overlap area do NOT cover Main PCB Wiring or Ground area, it’s suggested to reserve Min. 5mm apart from Module Antenna.
