hello, i am working with a long range ble long range transmitter and receiver which will communicate over long range to send a ble nus string in nrf52840, so i set tx power to +8 dBm and referred ble_app_att_mtu_throughput example to set phy to coded but am only getting line of sight range of 40 meters when verified tx speed in register Data rate and modulation(0x40001510) it's value is 0 but it should be 5 for 125kbit/s for coded phy.
please help me out to set phy to codded in Nordic uart central and peripheral example. to send nus string over long range.
