Thank you for your reply.

I later moved on_ble_evt and some code related to m_conn_handle to on_ble_peripheral_evt.

After removing some unnecessary code, it worked.

Hi Player777,

As you can see, the error message indicates an issue at a particular line in main.c. What is being done there? What is the context around that line of code?

Additionally, I modified the code within the for loop:
for (;;)
{
data_buffer[0] = 0x0A;
data_buffer[1] = 0x0B;
data_buffer[2] = 0x0C;
uint16_t length = 242;
uint32_t err_code = ble_nus_data_send(&m_nus, (uint8_t *)data_buffer, &length, m_conn_handle);
if((err_code != NRF_ERROR_INVALID_STATE) && (err_code != NRF_ERROR_BUSY) && (err_code != NRF_ERROR_NOT_FOUND))
{
APP_ERROR_CHECK(err_code);
}
idle_state_handle();
nrf_delay_ms(30);
}

The following error occurred:

<debug> nrf_ble_gatt: Requesting to update ATT MTU to 247 bytes on connection 0x1.
