I am trying to start the ATULPC-DEMO from the link below.
I have the board as under the link and downloaded firmware example from this page. The building of the project is successful, but BLE initialization fails.
The program fails in function at_ble_init() from file ble_manager.c with return code AT_BLE_BUS_TIMEOUT = 0xD1. No data appears on USART bus.
This demo should work because there are reports that it works, but it does not work on two my boards.
I use Atmel Studio 7, J-link v8, the power supply is 3V from USB via LDO.
Could somebody help with any advice? Any help would be appreciated.
