STM32WL33xx: How to increase the wakeup radio distance?

[Gwo]

What settings can be changed in LPAWUR_WakeupRadio_Rx code to increase the wakeup radio distance?

From data sheet ,  The STM32WL33xx RF output power can be programmed to deliver up to +20 dBm, in TX+TXHP mode, and in MRSUBG_WakeupRadio_Tx code,

MRSUBG_RadioInitStruct.outputPower = 20;
MRSUBG_RadioInitStruct.PADrvMode = PPA_DRV_TX_TX_HP;

The above changing is for TX side, what about RX side?

Hello @Gwo 

We have already implemented the optimal settings in the MX_LPAWUR_Init() function of the LPAWUR_WakeupRadio_Rx project. You can potentially increase the Tx output power, improve the matching network, or select a high-efficiency antenna.

Best Regards.
