I'm working with nRF Connect SDK (Zephyr). In that I am using 255 byte array to get response from nrf52832 through BLE. my code is getting crash in response back. when I decrease size of array to 50 byte it's working.
but when I compile same in nrf5 sdk code it's working properly with 255 bytes array. Can you provide any solution or workaround to get it work?
