Re: Packet transmission failure caused by Not enough space

Hello, when AP sends a package every 1 milliseconds, it is found that station and AP can't create links. see attschments send_log_1ms.rar,recv_log_1ms.txt. By grabbing data packets, it is found that AP rarely sends Beacon, Maybe AP does not have time to send Beacon. In this case, Beacon rarely leads...

Re: Packet transmission failure caused by Not enough space

I want to get the size of the buffer free. If I find that the size of the buffer is enough, I will send it or else it will not be sent. Is there a solution?

Packet transmission failure caused by Not enough space

Problem: AP as a UDP server,sends a broadcast packet with a size of 1440 bytes, which is sent every 10 milliseconds. After sending 80 packets, the number is recounted. There are 10 to 30 packets are sent by Not enough space. However, If you send packets once every 50 milliseconds, this is a complete...
