I get an error sometimes in my project, and the error code is 0xDEADBEAF always. it happens often when i start advertising and connectting to a mobile phone. i get the debug information through app_error_handler() method, sometimes the line_num is 0x293 ,the file_name is src\ll_adv.c ,sometimes the line_num is 0x562 ,the file_name is src\ll_lm.so.c ,sometimes the line_num is 0xae9 , the file_name is src\ll_slave.c. in my application GPIOTE_IRQHandler is called frequently,i don't know whether it is an important influencing factor

my project is developed in keil uVision4 basing on nrf51822, the sdk version is v7.1.0. And my phone OS is android v4.4.2, the app we developed is basing on nRFUART_Android4.3. i have uploaded a zip file named SmartTape-2015-08.zip,it's my project

which versions of nrf51822 are you using, the version number should be written on the black die of the nordic chip. It reads something like NRF51822 QFXXXXX (its little difficult to read)

it's QFAAG2

looking at your project it looks like it is from SDK6.1 not 7.1, is that right? you probably meant to say you used Softdevice 110 7.1 version
