正在研究传输数据用UART 还是SPI ?
如果 Wifi的速度不高(≤1MB/s), 那我们就用UART;
否则就用更高速的SPI
这些数据release notes里面都有的:
MCU-NWP SPI link
13 MHz
20 MHz
Init time from hibernate until device ready*
250 mSec
75 mSec
Init time from hibernate until WPA2 connection*
300 mSec
120 mSec
Maximum UDP throughput, open socket
13 Mbps
16 Mbps
Maximum TCP throughput, open socket
11 Mbps
13 Mbps
Maximum TLS/SSL throughput with RC4_128 cipher
5 Mbps
9 Mbps
Maximum TLS/SSL throughput with AES_256 cipher
7 Mbps
12 Mbps
Minimum TLS/SLL connection time with ECC cipher
2.5 Sec
1.3 Sec
Minimum TLS/SSL connection time with RSA cipher
200 mSec
130 mSec
如果穿数据的应用,一般都可以满足了,如果传输图像2路应该没问题。
