Hard fault by using UART? nRF52832https://devzone.nordicsemi.com/f/nordic-q-a/59576/hard-fault-by-using-uart-nrf52832Hello. I am using nRF52832, SDK ver 15.3 and running it as a peripheral device. I use an interval timer to send a UART to an external device and receive an ACK. After running it for a while, HardFault_Handler will be called as shown in the attached imageen-USTelligent Community 13Sat, 19 Oct 2024 12:01:33 GMTRE: Hard fault by using UART? nRF52832https://devzone.nordicsemi.com/thread/507002?ContentTypeID=1Sat, 19 Oct 2024 12:01:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0a8f4ed6-9ca6-486e-9d55-78bdf37a6918wjj<p>I have the same problem, do not know how to solve</p><div style="clear:both;"></div>RE: Hard fault by using UART? nRF52832https://devzone.nordicsemi.com/thread/242303?ContentTypeID=1Mon, 30 Mar 2020 07:57:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:05339dce-3f0f-43a2-b26a-e9ae7efe4a70Vidar Berg<p>Great!

Are you receiving any input on the UART, or just transmitting? </span></p><div style="clear:both;"></div>
