  - GPIOs disabled by default (`-1`) due to no physical connection; verified via jumper wiring and solder
- Network split scenarios

# $${\color{green} \text{2.11.3}}$$

## Bug Fixes

- made UART Hosted interface more stable:
  - flush the input after reset. Rx line may toggle while resetting the co-processor, causing Host UART to store invalid data.
  - 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

# $${\color{cyan} \text{2.11.0}}$$

## Bug Fixes

- remove double freeing of buffer if `chan_arr[buf_handle->if_type]->rx()` fails. Underlying rx function will free the memory

> [!WARNING]

# $${\color{cyan} \text{2.10.0}}$$

## Features: GPIO Expander

- **GPIO Expander**: Added feature to allow the host to control the GPIOs of the slave co-processor over the existing transport link. See [GPIO Expander Guide](./docs/gpio_expander.md).
- **GPIO Expander Example**: Added a new example `examples/host_gpio_expander` to demonstrate the usage of the GPIO expander feature.

## APIs Added

- `esp_hosted_cp_gpio_config`

# $${\color{green} \text{2.9.5 - 2.9.6}}$$

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

- fixed ESP-Hosted and SDIO issues that prevent transport reinitialisation
- fixed files to skip when running codespell during pre-commit

# $${\color{green} \text{2.9.3}}$$

## Bug Fixes

- removed setting `scan_method` and `sort_method` in co-processor when station is connecting. Use the values sent by the Host in the Wi-Fi config.

- Update Wi-Fi bandwidth enums for newer ESP-IDF compatibility

## Improvements

- Better validation and user-readable error messages for slave OTA
- Detect empty or uninitialized LittleFS and partition OTA sources
- Clear guidance when invalid or missing slave firmware binaries are detected

# $${\color{green} \text{2.9.0}}$$

## 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](https://www.google.com/search?q=https://github.com/espressif/esp-hosted-mcu/blob/main/docs/slave_light_sleep.md) 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).
  - Example: `examples/host_network_split__power_save/host_wakeup_demo_using_udp_packet`

## 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.
- **Timing & Reset Improvements**:
  - Adjusted task delays in the host wakeup sequence to prevent the host from receiving incorrect or premature reset signals during the wake-up transition.

---

# $${\color{red} \text{2.8.4}}$$

## Features: Slave Auto Light sleep

- Auto Invoked when host triggers deep sleep
- Example implementation in example_light_sleep.c

# $${\color{red} \text{2.8.3}}$$

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](https://components.espressif.com/components/espressif/esp_hosted/examples/host_peer_data_transfer):

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](https://components.espressif.com/components/espressif/esp_hosted/examples/host_peer_data_transfer)

## 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](https://github.com/espressif/esp-hosted-mcu/blob/main/docs/feature_network_split.md).

## Example: [Network Split with Host Power Save Example](https://components.espressif.com/components/espressif/esp_hosted/examples/host_network_split__power_save)

## **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](https://github.com/espressif/esp-hosted-mcu/blob/main/docs/feature_host_power_save.md)
- 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.
