https://test-devzone.nordicsemi.com/f/nordic-q-a/88689/nrf52840---ble-strength-range-weakHi Nordic team, We have just received our PCB prototypes with nRF52840 chip. While testing BLE functionality we found that the BLE is very weak. The connection is lost within 4/5 meters. We used to use nRF52833 and the range was a lot bigger.
