Regarding the RAK5860 examples found here, why at the beginning of each example, does the WB_IO2 pin get turned to Output and set to High? I can’t seem to find this in the documentation. Instead, the docs say WB_IO1 is the Power Key for this module, and we see this pin being toggled later in the sketch.
If WB_IO2 is beneficial to the operation of the RAK5860, I would recommend to include this in the module documentation for future reference.
Thank you @carlrowan, I feel very stupid. You are correct that the datasheet is abundantly clear: this pin is being turned on to enable the active GPS antenna.
