how to change the BLE data transmission rate in nrf52840 sdk s140?
Which smartphone are you using the nRF Connect mobile app on?
Does the phone support 2 mbps or coded phy?
You could configure this on your phone when you have connected to a peripheral device, and you click the connection's options button and select the Set Preferred PHY option.
Best regards,
