How to extend the communication distance of ESB in nRF52832

Hi,

I am developing the proprietary protocol by using ESB function in nRF52832.

If the linear distance between the two devices is less than 10 cm, normal communication is possible.
When the distance between two devices is greater than 1 meter, the RF signal will not be communicated even if I set the output power to "4dBm".

How can I solve it's problem?

Thank you

    I assume Andrew is currently unavailable, but I can confirm that you can use these two examples to test BLE communication between your two boards. 

    Please be aware that these examples use the physical UART on the nRF52 device to enter and receive UART information passed over the BLE link. This means you need to connect the UART interface of your modules to something. 

    On the nRF52832 DK this is handled automatically by the Segger chip on the DK, which sets up a virtual comport over the USB connection to the PC.

    Best regards
