HI,
Why I have this mistake with 👍

Which board you used? Which core version ?

[ebelouet]

stm32WL generic and generic WLE5C.

In fact I have STM32WLE5CCU6 chip.

Hi @ebelouet
You have to define the correct board configuration.
The library defines a default one for the Nucleo WL55JC1 as stated here:
https://github.com/stm32duino/STM32LoRaWAN/blob/192c1234a8661f72f1635e5675db0d11fb110920/src/BSP/radio_board_if.c#L41-L81

Example for RAK module:

Arduino_Core_STM32/variants/STM32WLxx/WL54CCU_WL55CCU_WLE4C(8-B-C)U_WLE5C(8-B-C)U/variant_RAK3172_MODULE.h

Lines 146 to 156 in cd3043f

	// LoRaWAN definitions
	#define LORAWAN_BOARD_HAS_TCXO 0U
	#define LORAWAN_BOARD_HAS_DCDC 1U
	#define LORAWAN_TX_CONFIG RBI_CONF_RFO_HP
	#define LORAWAN_RFSWITCH_PINS PB8, PC13
	#define LORAWAN_RFSWITCH_PIN_COUNT 2
	#define LORAWAN_RFSWITCH_OFF_VALUES LOW, LOW
	#define LORAWAN_RFSWITCH_RX_VALUES HIGH, LOW
	#define LORAWAN_RFSWITCH_RFO_LP_VALUES LOW, HIGH
	#define LORAWAN_RFSWITCH_RFO_HP_VALUES LOW, HIGH

So you have to define those definitions to be able to build and run properly.
You can add an file named hal_conf_extra.h and add your configuration, ex:

// LoRaWAN definitions
#define LORAWAN_BOARD_HAS_TCXO          0U
#define LORAWAN_BOARD_HAS_DCDC          1U
#define LORAWAN_TX_CONFIG               RBI_CONF_RFO_HP

#define LORAWAN_RFSWITCH_PINS           PB8, PC13
#define LORAWAN_RFSWITCH_PIN_COUNT      2
#define LORAWAN_RFSWITCH_OFF_VALUES     LOW, LOW
#define LORAWAN_RFSWITCH_RX_VALUES      HIGH, LOW
#define LORAWAN_RFSWITCH_RFO_LP_VALUES  LOW, HIGH
#define LORAWAN_RFSWITCH_RFO_HP_VALUES  LOW, HIGH

or a file named build_opt.h with:

-DLORAWAN_BOARD_HAS_TCXO=0U
-DLORAWAN_BOARD_HAS_DCDC=1U
-DLORAWAN_TX_CONFIG=RBI_CONF_RFO_HP
-DLORAWAN_RFSWITCH_PINS=PB8,PC13
-DLORAWAN_RFSWITCH_PIN_COUNT=2
-DLORAWAN_RFSWITCH_OFF_VALUES=LOW,LOW
-DLORAWAN_RFSWITCH_RX_VALUES=HIGH,LOW
-DLORAWAN_RFSWITCH_RFO_LP_VALUES=LOW,HIGH
-DLORAWAN_RFSWITCH_RFO_HP_VALUES=LOW,HIGH

thank, I will try this

Note that this is the value from the RAK variant, up to you to check the correct one for your board.
