  • check that offset in received payload header is valid: discard packet for invalid offsets.
  • check flags in received payload only after the payload is considered valid

{\color{green} \text{2.11.2}}

Minor fix: On Timeout/Failure, Print RPC req str instead of RPCId

{\color{green} \text{2.11.1}}

Minor fixes: const qualifier violations while building

{\color{cyan} \text{2.11.0}}

{\color{cyan} \text{2.10.0}}

Features: GPIO Expander

Using shorter, more manageable names for esp hosted events Before adoption, concise the event names from full string COPROCESSOR to just CP in event names

{\color{green} \text{2.9.4}}

Features

• enabled ESP-Hosted events. Host can register an event handler to receive these events from co-processor:
  • INIT event, indicating the co-processor has started
  • HEARTBEAT event, when enabled by the host
  • TRANSPORT_FAILURE event, when ESP-Hosted encounters a transport failure
  • host can use these events to determine if the co-processor rebooted (unexpected INIT event) or hanged (missing HEARTBEAT)
• added examples/host_hosted_events as an example to show how the host can use either event to reinitialise a Station connection to an AP

Bug Fixes

Improvements

• Better validation and user-readable error messages for slave OTA
• Detect empty or uninitialized LittleFS and partition OTA sources

{\color{green} \text{2.9.0}}

Bug Fixes

• Fix slave OTA failures on back-to-back updates by removing the hard dependency on CONFIG_ESPTOOLPY_FLASHMODE_QIO.
• Previously, mandating QIO flash mode caused consecutive OTA operations to fail; this is now resolved by removing the forced flash mode setting.

{\color{red} \text{2.8.5}}

Features: Light Sleep Integration & Documentation

• Light Sleep Documentation: Added comprehensive Light Sleep Integration Guide detailing the handshake between host power states and slave light sleep.
• Smart Wakeup Demo: Added a new demo showcasing the slave waking the host MCU using specific network triggers (UDP packets).

Bug Fixes & Stability

• Memory Leak Fixes:
  • Resolved memory leaks in the SDIO driver during unload/deinit by ensuring proper buffer cleanup and sdio_slave_send_get_finished usage.
  • Fixed memory leaks in esp_hosted_cli by adding proper deregistration APIs for Hosted-specific commands.
  • Cleanly handled timer memory removal in the Host Power Save component.
• Concurrency & Race Conditions:
  • Added semaphore protection (mutex) in host_power_save.c to prevent race conditions when multiple threads attempt to wake the host simultaneously.

{\color{red} \text{2.8.3}}

Add up mutex protection for callback array for Peer Data Transfer

{\color{red} \text{2.8.2}}

Amend Peer Data Transfer example with custom msg id

Amend Peer Data Transfer Example:

Features:

• User can register callback-based dispatch for their own msg ids, both at host and slave
• Configurable handler slots via Kconfig (default: 3)

API:

• esp_err_t esp_hosted_send_custom_data(uint32_t msg_id, const uint8_t *data, size_t data_len)
• esp_err_t esp_hosted_register_cu stom_callback(uint32_t msg_id, void (*callback)(uint32_t msg_id, const uint8_t *data, size_t data_len));

Example (examples/host_peer_data_transfer):

• Uses animal sound theme (CAT→MEOW, DOG→WOOF, HUMAN→HELLO)
• Host sends CAT_MSG_ID, with byte stream. Slave sends back same stream with MEOW_MGD_ID and so on.

Configuration:

• Host: CONFIG_ESP_HOSTED_MAX_CUSTOM_MSG_HANDLERS (Kconfig)
• Slave: CONFIG_ESP_HOSTED_MAX_CUSTOM_MSG_HANDLERS (Kconfig.projbuild)
• Ported as H_MAX_CUSTOM_MSG_HANDLERS on host side

Allow to disable app_main() from slave

Kconfig : CONFIG_ESP_HOSTED_COPROCESSOR_APP_MAIN at coprocessor menuconfig

• Default: Enabled (for slave example from registry)
• Purpose: Controls whether ESP-Hosted provides its own app_main()
• When to disable:
  • Using ESP-Hosted slave code base as a component in your application

{\color{red} \text{2.8.1}}

Example: Peer Data Transfer Example

Features

• Supports sending and receiving arbitrary (preformatted) user data from/to host and slave
• Maximum payload size: 8166 bytes per packet

APIs

• esp_hosted_send_custom_data(data, length): Send raw binary data to coprocessor
• esp_hosted_register_rx_callback_custom_data(callback): Register callback for receiving custom data

{\color{red} \text{2.8.0}} - Network Split (Shared IP)

Network Split (Shared IP)

This major update allows the Host MCU and the ESP Slave to share a single IP address while running independent network stacks. This is ideal for low-power products where the Slave handles background tasks while the Host sleeps.

• Disabled by default. Enable using CONFIG_ESP_HOSTED_NETWORK_SPLIT_ENABLED config
• Documentation: Network Split Guide.

Example: Network Split with Host Power Save Example

Key Additions

• Smart Traffic Routing: nw_split_router.c automatically directs traffic through function, nw_split_filter_and_route_packet()
• Port-based (TCP/UDP): Uses CONFIG_LWIP_TCP_LOCAL_PORT_RANGE and CONFIG_LWIP_UDP_LOCAL_PORT_RANGE to decide if the Host or Slave handles a packet.
• Reserved Ports: Mandate packets on specific ports (e.g., 80, 443) to the Host via CONFIG_ESP_HOSTED_HOST_RESERVED_PORTS_CONFIGURED.
• Non TCP/UDP: Built-in handling for ARP, ICMP, and DHCP on coprocessor (configurable) to offload host for other priority work or deep sleep
• iperf Performance
  • Demo of sharing same port: Port 5001 is shared smartly, allowing performance testing on either stack (at a time) without reconfiguring.
• Low-Power Support
  • (Optionally) Deeply integrated with Host Power Save
• Smart Wakeup demo
  • The Slave can "wake up" the Host when it receives specific traffic or an MQTT message containing the "wakeup-host" string.
• Collision Prevention
  • Added esp_hosted_lwip_src_port_hook.h to ensure the Host and Slave never try to use the same source port.
• Supported Targets
  • Slaves: ESP32-C5, C6, S2, S3.
  • Hosts: ESP32-P4, H2, and non ESP MCUs.
