WBE2R-R-ZIGBEE v.2 known issues

ERRWBE2RRZIGBEEV20001: Low transmit power

Affected devices

WBE2R-R-ZIGBEE v.2 all batches up to and including v2.4A.

If you cannot inspect the module revision, identify its version from the console:

Connect to the controller over SSH.
Run the command (zigbee2mqtt must be running):
```
mosquitto_sub -t zigbee2mqtt/bridge/info | grep -oP '"type":\s*"zStack[^"]*"|"revision":\s*\d+'
```
The response will contain:
- "type":"zStack3x0" — this is WBE2R-R-ZIGBEE v.2;
- "revision":2022MMDD or "revision":2023MMDD — the firmware must be updated.
After the firmware update, the type value remains unchanged, while the "revision" field will contain version 2024MMDD or later.
Stop the command by pressing Ctrl+C.

Description

Low transmit power from WBE2R-R-ZIGBEE v.2 to sensors/routers. At a critical distance, sensor data still reaches WBE2R-R-ZIGBEE v.2, but signals from the module no longer reach the sensor/router. Changing transmit power in the zigbee2mqtt configuration has no effect.

Cause and details

The problem is caused by using the unsuitable CC1352P2_CC2652P_other_coordinatorfirmware. This firmware controls power through microcontroller pins DIO_6 and DIO_5, which are unused on this module. The correct CC1352P2_CC2652P_launchpad_coordinator firmware uses the correct pins, DIO_28 and DIO_29, to control transmit power.

Workaround

Update the WBE2R-R-ZIGBEE v.2 firmware following the instructions.

Fix

Fixed in newer WBE2R-R-ZIGBEE v.2 modules, starting with batch v2.4A/1.
