Global coap_build_hdr (coap_udp_hdr_t *hdr, unsigned type, const void *token, size_t token_len, unsigned code, uint16_t id): Use coap_build_udp_hdr instead
Global coap_build_reply (coap_pkt_t *pkt, unsigned code, uint8_t *rbuf, unsigned rlen, unsigned max_data_len): Use coap_builder_init_reply instead.
Global coap_hdr_data_ptr (const coap_udp_hdr_t *hdr): Use coap_get_token() instead
Global coap_hdr_get_token (const coap_udp_hdr_t *hdr): This function was introduced to keep legacy code alive. Introducing new callers should be avoided. In the RX path an coap_pkt_t will be available, so that you can call coap_get_token instead. In the TX path the token was added by us, so we really should know.
Global coap_hdr_get_token_len (const coap_udp_hdr_t *hdr): This function was introduced to keep legacy code alive. Introducing new callers should be avoided. In the RX path an coap_pkt_t will be available, so that you can call coap_get_token instead. In the TX path the token was added by us, so we really should know.
Global coap_hdr_len (const coap_udp_hdr_t *hdr): This function was introduced to keep legacy code alive. Introducing new callers should be avoided. In the RX path an coap_pkt_t will be available, so that you can call coap_get_total_hdr_len instead. In the TX path the header was created by us (e.g. using coap_build_hdr which returns the header size), so we really should know already.
Global coap_hdr_set_code (coap_udp_hdr_t *hdr, uint8_t code): Use coap_pkt_set_code instead
Global coap_hdr_set_type (coap_udp_hdr_t *hdr, unsigned type): Use coap_pkt_set_type instead
Global coap_hdr_t: Avoid using low level types in your application, but rather use the zero overhead wrappers and work on coap_pkt_t instead.
Global coap_parse (coap_pkt_t *pkt, uint8_t *buf, size_t len): Use coap_parse_udp instead
Global coap_pkt_t::hdr: Use coap_pkt_t::buf to access the underlying buffer. Use helpers such as coap_get_code_raw to parse the contents in a transport agnostic way.
Global CONFIG_EFM32_XTIMER_USE_LETIMER: This option is deprecated and should be replaced by CONFIG_EFM32_ZTIMER_USE_LETIMER.
Global CONFIG_GNRC_IPV6_STATIC_LLADDR_IS_FIXED: Will be removed after release 2025.07 - after this the static link-local address will always be fixed unless a use-case for the auto-increment can be found.
Global gcoap_request_memo_get_hdr (const gcoap_request_memo_t *memo): Use gcoap_request_memo_get_buf instead
Global NETDEV_EVENT_TX_COMPLETE_DATA_PENDING: Issue an NETDEV_EVENT_TX_COMPLETE event instead and pass the data pending info in netdev_driver_t::confirm_send via the info parameter
Global NETDEV_EVENT_TX_MEDIUM_BUSY: Issue an NETDEV_EVENT_TX_COMPLETE event instead and return -EBUSY in netdev_driver_t::confirm_send.
Global NETDEV_EVENT_TX_NOACK: Issue an NETDEV_EVENT_TX_COMPLETE event instead and return -EHOSTUNREACH in netdev_driver_t::confirm_send. Via the info parameter additional details about the error can be passed
Module pseudomodule_sema_deprecated: Will be removed after the 2021.07 release.
Global saul_class_to_str (const uint8_t class_id): Use saul_class_print or saul_class_write instead
Global sema_wait_timed (sema_t *sema, uint64_t timeout): Will be removed after release 2021.07
Global SPIClass::setBitOrder (uint8_t order): This function is deprecated in the official Arduino API, so it is a good idea to not use it. In RIOT, this function is not yet scheduled for removal to allow using Arduino libraries using it.
Global SPIClass::setClockDivider (uint8_t divider): This function is deprecated in the official Arduino API, so it is a good idea to not use it. In RIOT, this function is not yet scheduled for removal to allow using Arduino libraries using it.
Global SPIClass::setDataMode (uint8_t mode): This function is deprecated in the official Arduino API, so it is a good idea to not use it. In RIOT, this function is not yet scheduled for removal to allow using Arduino libraries using it.
Global stdin_isrpipe: Use stdio_rx_write or stdio_rx_write_one. This isrpipe will become private and should not be used directly. Using this isrpipe directly will not work with the stdio_notify module. Will be removed after the 2027.01 release.
Module sys_shell_commands_gnrc_udp: Use UDP shell command instead. will be removed after the 2026.10 release.
Module sys_xtimer: xtimer has been deprecated in favor of the ztimer high level timer abstraction layer
Global THREAD_CREATE_STACKTEST: will be removed after 2025.07 release
