1. A method comprising:
indicating and adapting a data rate associated with a data packet to be transmitted from a transmitting device to a receiving device in a Bluetooth long-range wireless network, wherein the data packet comprises a preamble, a first packet portion, and a second packet portion;
encoding the first packet portion using a first modulation and coding scheme (MCS) in accordance with a first data rate, wherein the first packet portion comprises an access address field and a rate indication field, wherein the access address field and the rate indication field are convolution forward error correction (FEC) encoded with a predetermined rate;
encoding the second packet portion using a second modulation and coding scheme (MCS) in accordance with a second data rate based on a value of the rate indication field; and
transmitting the data packet to the receiving device in the wireless network.
