Texas Instruments provides a recommended PCB layout in the CC2564BYFVT datasheet, but it's also recommended to follow the guidelines in the TI's 'Antenna and PCB Design for CC256x' application note (SWRA419).
Optimizing the antenna design involves considering factors such as antenna type, size, and placement. TI provides antenna design guidelines in the CC2564BYFVT datasheet and the 'Antenna and PCB Design for CC256x' application note (SWRA419).
The maximum transmit power of the CC2564BYFVT is +20 dBm (100 mW) for Bluetooth BR/EDR and +10 dBm (10 mW) for Bluetooth Low Energy (BLE).
TI provides guidelines for coexistence in the CC2564BYFVT datasheet and the 'Coexistence of CC256x with Other Wireless Technologies' application note (SWRA420).
The power consumption of the CC2564BYFVT varies depending on the mode: Rx mode: 90 mA, Tx mode: 120 mA, Idle mode: 10 mA, and Sleep mode: 1.5 mA (typical values).
