/*Defines for minimal and maximal RX buffer size. This size includes the spi
|
|
header and hci header.
|
|
The maximal buffer size derives from:
|
|
MTU + HCI header + SPI header + sendto() agrs size
|
|
The minimum buffer size derives from:
|
|
HCI header + SPI header + max args size
|
|
|
|
This buffer is used for receiving events and data.
|
|
The packet can not be longer than MTU size and CC3000 does not support
|
|
fragmentation. Note that the same buffer is used for reception of the data
|
|
and events from CC3000. That is why the minimum is defined.
|
|
The calculation for the actual size of buffer for reception is:
|
|
Given the maximal data size MAX_DATA that is expected to be received by
|
|
application, the required buffer is:
|
|
Using recv() or recvfrom():
|
|
|
|
max(CC3000_MINIMAL_RX_SIZE, MAX_DATA + HEADERS_SIZE_DATA + fromlen
|
|
+ ucArgsize + 1)
|
|
|
|
Using gethostbyname() with minimal buffer size will limit the host name
|
|
returned to 99 bytes only.
|
|
The 1 is used for the overrun detection
|
|
|
|
Buffer size increased to 130 following the add_profile() with WEP security
|
|
which requires TX buffer size of 130 bytes:
|
|
HEADERS_SIZE_EVNT + WLAN_ADD_PROFILE_WEP_PARAM_LEN + MAX SSID LEN + 4 * MAX KEY LEN = 130
|
|
MAX SSID LEN = 32
|
|
MAX SSID LEN = 13 (with add_profile only ascii key setting is supported,
|
|
therfore maximum key size is 13)
