hello,
I use nrf51822 + S130 + SDK12.2 in my product, nrf51822 work at central + peripheral mode，and i use nrf_duf_flash module for my dfu funtion.
The problem is, i use my dongle(as central role) connect my product(as peripheral role) and send dfu commands to it, when my product do not connect a peripheral as central role, it looks like work well, the dfu process is ok, but when my product do connect a peripheral as central role(that means my product has to connection both as central and peripheral), some times the dfu is ok, but some times, program will dead in nrf_flash_wait function，in the loop
while ((m_flags & FLASH_FLAG_OPER) != 0)
{
(void)sd_app_evt_wait();
}
and never out.
my dfu code like this:
if (nrf_dfu_flash_store((uint32_t *)(IAP_STORE_ADDR + s_tIAPState.write_ptr), (uint32_t *)data_buf, (data_len >> 2), NULL) != FS_SUCCESS)
{
tCmdPar.index = IAPERROR_WRITEFLASH;
}
else
{
if (nrf_dfu_flash_wait() != FS_SUCCESS)
{
tCmdPar.index = IAPERROR_WRITEFLASH;
break;
}
//other code
}
I also try SDK12.3, the problem is same.
Is this a bug of SDK? How can i fix it, or, if do not use nrf_dfu_flash module, what can i do?
