Expected behavior
Hello,
we setup a system with the ESP32-S3 and the esp_hosted_fg. It is a regular feature to start and stop the soft-ap without reset of the host controller.
The soft-ap was started, used and stopped. The soft-ap is now started again and the WiFi communication is expected, because a WiFi client is connected and sends UDP data packets. It is expected, that the lwip stack on the host receives the packets.
Actual behavior (suspected bug)
The soft-ap is now started again and the WiFi communication is expected, because a WiFi client is connected and sends UDP data packets. The received data packet is dropped by the function netdev_rx. The value ndev->state has NETDEV_STATE_DOWN.
I detected an bug in the following function. When the host driver shall start the soft-ap again, then the rx_q is already created. The case of the condition if (ndev->rx_q) do not update of the ndev->state.
int netdev_open(netdev_handle_t ndev)
{
if (!ndev)
return STM_FAIL;
if (ndev->rx_q) {
xQueueReset(ndev->rx_q);
return STM_OK;
}
ndev->rx_q = xQueueCreate(RX_QUEUE_SIZE, sizeof(struct esp_pbuf));
if (!ndev->rx_q)
return STM_FAIL;
ndev->state = NETDEV_STATE_UP;
return STM_OK;
}Error logs or terminal output
Steps to reproduce the behavior
- start soft AP
- communication with client is possible
- stop soft AP
- start soft AP
- communication with client is not possible
