Hello,
I am using nRF51422 DK running on SDK v12.3.0. I am migrating the project examples/ble_central/ble_app_uart project from Keil uVision to Segger Embedded Studio using this guide.
Upon build, I did not have any compile errors but did receive Linker errors as shown on the image below.
Building ‘ble_app_uart_c_pca10028_s130’ from solution ‘ble_app_uart_c_pca10028_s130’ in configuration ‘nrf51422_xxac’
