I just resumed from work from a few months ago with the CC2540 keyfob and iPhone app. Weird, I can't seem to get the iPhone app (TI-BLE-demo) to recognize the keyfob when I load it with "cc2540_ble1.1_keyfob_SimpleBLEPeripheral.hex" or even the "CC2540MiniDkDemoSlave.hex" found on another posting. More specifically, the keyfod doesn't look like it is even running...I see no led light up. Just for these images. The basic "cc2540_ble1.1_SmartRF_SimpleBLEPeripheral.hex" runs, however (and the iPhone app can discover it...just doesn't like the services/characteristics it finds).
Hmmm, bad flash? I don't see any flash errors when programming, although I do get an error when verifying (eh, but I get that for the images that work, too).
Any ideas out there before I order a new eval kit from DigiKey?
