I’m working with modules S3B (digi 900MHz) and I have actually 2 problems. First, after setting (with the XCTU software) the gpios in SPI mode, I can’t access it again with XCTU serial detection.
Secondly, when i access them through the radio with another module, I can’t disable the SPI gpios.
It returns for example (to disable SPI_ATTN):
"Error writing the following AT parameters:
-D1: Status Error
firmware version is 8075.
Any help or idea would be appreciated.
