Hi,
We are trying ble_app_uart example for nRF51822 with nRF5 SDK v12.3 and ble_app_uart_pca10028_s130.hex file provided from hex folder works fine, but when we open IAR project ble_app_uart.eww and compile and make it, resulting .hex file is significantly smaller from previous one and doesn't work when flashed on device. What can be the problem?
