Lora (V4) Radio and Oled together

#1

I have a System that uses the Lora node. Originally it used the V2, and worked great, When V2 became obsolete I upgraded the hardware and software of my system to meet the new V3 pinouts and firmware, that works great, now I am attempting to upgrade to the V4 board.
I have updated my Arduino libraries and boards and all is ok there.
My code compiles and loads into the V4 board ok, but the OLED does not display
Removing the MCU.begin from my setup makes the Oled work, but then the radio does not work?
What is the solution to using both the Oled and the radio together, is there a new Oled method needed as there was between V2 and V3?

Please check the serial port to see if the LoRa chip ID is inactive.

Hi Richard, Chip is registered

Ok, Issues have now been resolved,
When transferring from V3 to V4 a lot of the GPIO pins have been reallocated to different functions
Where when using a V3 board I used GPIO2 GPIO20 and GPIO26 as outputs to control peripheral equipment, these three GPIO’s are now used for controlling the Oled and Power to the radio etc so that my original code was holding these lines which now need to be left to the firmware to control.
This means yet another board redesign for me to allocate those outputs to other GPIO’s that are free.
Fortunately that is easy enough and the code ended up being able to be ported more or less unaltered other than those GPIO’s

Chip is registered, not the issue
