Added in 11.0.0#
Bi-directional Green Power support with CMP Zigbee NCP + OpenThread RCP#
Added bi-directional Green Power support with CMP Zigbee NCP + OT RCP configuration, enabling Green Power Proxy functionality in NCP-RCP multiprotocol applications.
Enhancements#
Added in 11.0.1#
In CMP applications, the RAIL MUX now dynamically switches to each protocol's individually configured TX power when that protocol is actively transmitting. Previously, all co-existing 15.4 protocols were constrained to the minimum TX power across all protocol configurations. Additionally, new CLI commands txpower and txpower_set <dBm> are available in CMP applications to independently get and set the OpenThread TX power.

Bug Fixes#
Fixed in 11.0.1#
| ID | Issue Description | GitHub / Salesforce Reference (if any) | Affected Software Variants, Hardware, Modes, Host Interfaces |
|---|---|---|---|
| 1569320 | Fixed an issue where CPCd could crash after a BLE scan with an active OT network in the ot-ncp-ftd-ble-rcp application. Updated SL_BTCTRL_RTOS_LINK_LAYER_TASK_STACK_SIZE to 1100 for Series 2 devices. Note: RTOS stack sizes require tuning as needed. | N/A | ot-ncp-ftd-ble-rcp app on Series 2 devices |
| 1569847 | Fixed an issue where gp_transmit_complete_event was not executed in a timely manner due to the Zigbee RTOS task not waking up, causing intermittent bi-directional Green Power commissioning failures. | N/A | CMP Zigbee NCP + OpenThread RCP app with Bi-directional Green Power support |
Fixed in 11.0.0#
| ID | Issue Description | GitHub / Salesforce Reference (if any) | Affected Software Variants, Hardware, Modes, Host Interfaces |
|---|---|---|---|
| 1471746 | Fixed an issue where the Zigbee + Bluetooth NCP application examples did not appear in Studio. | N/A | Zigbee + Bluetooth NCP app |
| 1524505 | Fixed an issue that could pass an invalid mac layer packet to cause an assert. | N/A | All OPNs, boards, modes and interfaces |
| 1568095 | Changed default SL_BT_CONTROLLER_BUFFER_MEMORY value for OpenThread NCP + BLE RCP application to work on parts with 96kB RAM. | N/A | OpenThread NCP + BLE RCP app |
Chip Enablement#
Added in 11.0.1#
None.
Added in 11.0.0#
xGM270S Leopard SiP Module: Added GA software support for xGM270S Leopard SiP Module.
xG301 Explorer Kit and Pro-kit Support: Added support for Explorer Kit and Pro-kit boards for xG301 devices.
