Have you enabled the PA/LNA for this Module as described at page#16 of the Module datasheet ?
Our application in "CYBLE-224110-EVAL EZ-BLE™ PSoC XT/XR Evaluation Board", works fine (considering the BLE Tx Power, BLE has range > 5meters) . The same application(with the corresponding pinouts modifications) in our board, make Bluetooth Link with less range (<2cm) , Tx pwr 0dBm.
Our conserning is to use BLE with lower power consuption as possible without using Extended Range Feature . Is it nessesary to programing PA/LNA to be in Bypass mode (which
ensures that the RF signal reaches the antenna as reported in PAGE16 )? Or it is the default configuration of CSD - PA/LNA to be in Bypass mode?
We are trying to figure out, what it going wrong, we believe that it is only the Host PVB Keep-Out Area Around the chip Antenna that cause the limited bluetooth range.

It is mandatory to configure/Enable the PA/LNA to reach the signal to antenna. For saving the power you can configure CSD/CPS pins further as mentioned in datasheet.
The range you are getting is just because of leakage current in Antenna pin.
We appreciate your guidelines in BLE configuration. Actually with LNA/PA standby mode and TxPower -6dBm we have 1m service area.
Again thank you very much.
