nRF9160 Lora SPI

[isurki]

Dear Community;

We are trying to send data via Lora using a nRF9160. The Lora transreceiver we are using is a RFM95W(Semtech SX1272). There are samples of code to receive and send messages under /zephyr/samples/drivers/lora/ . I can open any of those prejects with SEGGER but not compile them. It pops up this error: 

"No default LoRa radio specified in DT"

We don´t know how to specify Lora device in DT, so far we have tried this in .overlay:

&spi3 { 
    compatible = "nordic,nrf-spim"; 
    status = "okay";
    sck-pin = <20>;
    mosi-pin = <21>;
    miso-pin = <22>;
    cs-gpios = <&gpio0 19 GPIO_ACTIVE_LOW>;
};

and this in prj.conf:

CONFIG_LOG=y
CONFIG_SPI=y
CONFIG_GPIO=y
CONFIG_LORA=y
CONFIG_LORA_SX12XX=y
CONFIG_PRINTK=y
CONFIG_SPI_3=y

Any help is appreciated.

Regards.

Hi,

That worked and now I am able to run the send example. I need to try receive example when I get another transreceiver.

Thank you so much, 

Best regards.
