Solution - Pin 41 on the XIAO ESP32S3 connects to NSS on the SX1262 via the B2B connector (sense) . The pin is active LOW for Chip Select (CS/NSS) it needs to be held high via a 10K ohn resistor. Pin 41 isn’t physically accessable on the ESP32S3. So if you couple the boards together via the B2B connector the only way to hold it high is solder a lead from NSS on SX1262 to 3v3 via 10K resistor.
It’s only an issue if you want to achive ~20uA Deep Sleep current.
Hope that helps someone !
