Hi,
I have a problem on the LoRa transmission.
If I use STM32F103 on SPI 1, LoRa transmission works.
And if I use the STM32G070 with the same code the LoRa transmission doesn't work.
What is the différence on the SPI in the STM32G070 ?

Perhaps subtle differences in the CS fall and raise with respect to the data. Watch for things like the FIFO and data clearing the wire.
