Hello, I encountered a problem while using the nrf5 SDK. In my software, I used a UART for debugging data output, a libuarte library for command output, and an app_button library to use my buttons. Since libuarte needs to dynamically switch the baud rate for command output, I found that when I reinitialized libuarte and then changed the baud rate and reinitialized it, an error occurred: <error> app: ASSERTION FAILED at F:\kiki\test_app\aqp-arp-test\modules\nrfx\drivers\src\nrfx_gpiote.c:473. However, when I commented out buttons_init and switched, this error did not occur and the baud rate could be switched normally. What could be the reason for this?
Thanks
