Lora project

[ro85ac]

I have the new T-SIM7000G board including Lora shield. I have tried both examples "sender" and "received" and I am getting the same output:

rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) configsip: 0, SPIWP:0xee clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00 mode:DIO, clock div:2 load:0x3fff0018,len:4 load:0x3fff001c,len:1044 load:0x40078000,len:10124 load:0x40080400,len:5828 entry 0x400806a8

What am I doing wrong?

After digging more it seems that the error is related to this line of code: "SPIClass SPI1(HSPI);" But without SPI1 I cannot se the SPI to Lora: "LoRa.setSPI(SPI1);"

Probably it's related to the SPI version and/or the dependent library https://github.com/sandeepmistry/arduino-LoRa

If I am not declaring SPI1 and initialize SPI with the pins of SPI1 (lora ones) I am getting the following error: Setup Lora freq : 868000000 LORA Begin FAIL

With the latest code the project works.
