BOOSTXL-AOA: BLE AOA system

Hi Carlo,

Our customer is developing a BLE AOA system with CC2640R2F and BOOSTXL-AOA antenna

TI has made the decision to discontinue further development and support of the TI-proprietary Angle of Arrival (AoA) on the CC2640R2. We recommend and welcome our customers using AoA on CC2640R2 to transition from the CC2640R2 to the new RTLS examples based on the Bluetooth 5.1 specification which can be used with the CC13x2R and CC26x2R devices. These software examples can be found in the SimpleLink CC13x2 and CC26x2 software development kit 3.40 or later which features a Bluetooth 5.1 qualified stack with support of Bluetooth 5.1 Angle of Arrival. To make this transition, here is a list of available resources you can reference: Simple Link Academy, AoA stack users guide, LaunchPad Tool Order Page.

What is the maximum distance between sender and receiver that they can communicate by BLE?

The answer will depend on the environment, the TxPower, the antenna gain, the PHY, etc. Please review our RF-RANGE-ESTIMATOR tool for a proper estimation.

Note: when using AoA, only the 1M PHY can be used.

What is the optimal distance range (max and min) between sender and receiver that the receiver can give accurate AOA data?

The answer will depend on the environment, the TxPower, the antenna type, the algorithms used, the accuracy expected, etc.

I hope this will help,

Best regards,
