CC2540EMK-USB: Connection to many slaves

Part Number: CC2540EMK-USB
Other Parts Discussed in Thread: CC2642R, CC2540

Hi Team,

We would like to confirm some information. Whether they can be connected to at least 4 slave devices and provision to connect to an external antenna. We would also like to confirm if USB2 or USB3 was used on the design.

Hoping for your assistance.

Thank you very much.

Regards,

Mark

The maximum connection is defined by MAX_NUM_BLE_CONNS which is 3 by default. If you need at lease 4 slave devices connection, I would suggest you to move to more powerful SOC such as CC2640R2 or CC2642R.

The USB IP on CC2540 support USB full speed only which is a part of USB 2.0 spec. I believe all hosts should be backwards compatible.
