Hello, I seem to have an issue with an SD card and LORA radio(RFM95, 915E6) using the same SPI bus.
The ESP32 is configured as
MOSI IO23(37)
MISO IO19(31)
SCK IO18(30)
CS SD Card IO4(26)
CS LORA IO5(29)
The LORA also uses other pins for support.
The SD card reads and writes, but there doesn’t seem to be any connection to LORA. I tried using an ESP8266 and it does work using Sandeep Mistry library.
Has any one else had this issue? Is there something which I should be concidering?
Also has anyone had any luck using the Radio Head libraries?
Thank you

Hi Rob.
Have you tested using your LoRa module without the SD card?
What exactly doesn’t work (does it fail to begin?)?
Have you tried the simple LoRa project: https://rntlab.com/esp32-lora-sender-and-receiver/
