I had taken the BLE_OTA_External_Memory_Bootloader and bootloadable projects and modified it to use an EEPROM device. I had it working, but now when I try and download the firmware via the CySmart tool I get an authentication error message.

There are no error messages on the UART console. I've added some additional printouts:
Bluetooth On, StartAdvertisement with addr: 00a0502c4623
Entering bootloader mode
BootloaderEmulator_Start
BootloaderEmulator_HostLink
Waiting for command
Updating BLE message with scaled values
Connected
CyBle_L2capLeConnectionParamUpdateRequest API: 0x00
EVT_GAP_DEVICE_DISCONNECTED
Updating BLE message with scaled values
Connected
CyBle_L2capLeConnectionParamUpdateRequest API: 0x00
EVT_GAP_DEVICE_DISCONNECTED
I've gone back and compared all of the settings between the bootloadable project and my project and they appear to be identical. Has anyone else seen anything like this.
Thanks.
Nick
