Connection between CC2540 Mini Development Kit and a mobile phone
How could I establish a communication between a CC2540 Mini Development Kit and a mobile phone.
The 2540 would need to talk to a phone which has Bluetooth low energy support. Until these phones are available, you can look into attaching the USB dongle in the mini-kit to the USB port on a phone(host mode) and develop apps on that. This method would be similar to the setup as defined in the mini-kit where you communicated between the PC (attached USB 2540) and the KeyFob(2540).
Yeah, I would suggest using the typical Bluetooth V2.1 until dual mode modules are standard on smartphones.
Can we use a BT V4.0 in CC2540 with "downward compatibility mode" sort of thing? I mean is there any way to ask this slave bluetooth device to talk with Master V3 or V2 bluetooth phones?
The CC2540 and CC2541 are single mode Bluetooth v4.0 Low Energy (BLE) devices can only communicate with other BLE devices. It is not compatible with previous Bluetooth standards. Apple iOS and Motorola Razar are two devices where there are examples and sample code available.
You can download them by visiting the TI BLEwiki page.
For Bluetooth BR/EDR there are other options available such as the CC256x which offers single and dual mode Bluetooth and BLE. There are wireless connectivity development kits available on the estore.ti.com that will allow you quickly develop apps that can talk to standard Bluetooth devices.
