    Hi All, Just wonder if there has been any progress on smartphone that can support BLE (for my test with the CC2540)? Apple released the iPhone 4S with BLE but as I understand they would not let my App play with their hardware... is that correct? When can I have an Android BLE prototype phone? Suggestions...

    Hi, I've been trying out the HIDDongle and Emulated Keyboard demo on the CC2540DK-MINI. But it is stated that these 2 projects "are not compliant with any Bluetooth specification". Does that mean they are not compliant to the BLE HID profile released recently? Does TI plan to make...

    We have a product that would need to be a master (initiator) in one role and automatically switch to slave (advertiser) in another role. The role change would be initiated by external stimulus input. Is this possible to do using the CC2540 chip?

    Richard Dolf
    In the simpleBleCentral project, in simpleBleCentral.c, when simpleBLECentralEventCB() receives the GAP_LINK_ESTABLISHED_EVENT, it doesn't call GATT_DiscPrimaryServiceByUUID() directly, but rather starts a one second timer to delay service discovery. Is this logic and delay really required for discovery...

  • Forum Post: CC2540 use PM2 mode and Timer1 at the same time

    tomoyuki
    Hello all. My application with CC2540 needs both PM2 low power mode and Timer1 operation. Timer1 should count up per 0.1msec. But I think when CC2540 is under PM2, it cannot operate any 32MHz Oscillators. So do you have any suggestions to use PM2 and Timer1 simultaneously?
