6LowPAN options list
#define LWIP_6LOWPAN_802154_HW_CRC 0 |
Set this to 1 if your IEEE 802.15.4 interface can calculate and check the CRC in hardware. This means TX packets get 2 zero bytes added on transmission which are to be filled with the CRC.
#define LWIP_6LOWPAN_CALC_CRC | ( | buf, | |
len | |||
) | lowpan6_calc_crc(buf, len) |
If LWIP_6LOWPAN_802154_HW_CRC==0, this can override the default slow implementation of the CRC used for 6LoWPAN over IEEE 802.15.4 (which uses a shift register).
#define LWIP_6LOWPAN_INFER_SHORT_ADDRESS 1 |
LWIP_6LOWPAN_INFER_SHORT_ADDRESS: set this to 0 to disable creating short addresses for matching addresses (debug only)
#define LWIP_6LOWPAN_IPHC 1 |
LWIP_6LOWPAN_IPHC: set this to 0 to disable IP header compression as per RFC 6282 (which is mandatory for BLE)
#define LWIP_6LOWPAN_NUM_CONTEXTS 10 |
LWIP_6LOWPAN_NUM_CONTEXTS: define the number of compression contexts per netif type
#define LWIP_LOWPAN6_802154_DEBUG LWIP_DBG_OFF |
Debug level for 6LoWPAN over IEEE 802.15.4
#define LWIP_LOWPAN6_DEBUG LWIP_DBG_OFF |
Debug level for 6LoWPAN in general
#define LWIP_LOWPAN6_DECOMPRESSION_DEBUG LWIP_DBG_OFF |
LWIP_LOWPAN6_DECOMPRESSION_DEBUG: enable decompression debug output
#define LWIP_LOWPAN6_IP_COMPRESSED_DEBUG LWIP_DBG_OFF |
LWIP_LOWPAN6_IP_COMPRESSED_DEBUG: enable compressed IP frame output debugging
#define LWIP_RFC7668_IP_UNCOMPRESSED_DEBUG LWIP_DBG_OFF |
LWIP_RFC7668_IP_UNCOMPRESSED_DEBUG: enable decompressed IP frame output debugging
#define LWIP_RFC7668_LINUX_WORKAROUND_PUBLIC_ADDRESS 1 |
LWIP_RFC7668_LINUX_WORKAROUND_PUBLIC_ADDRESS: Currently, the linux kernel driver for 6lowpan sets/clears a bit in the address, depending on the BD address (either public or not). Might not be RFC7668 conform, so you may select to do that (=1) or not (=0)
