The hardware of the SX126x chips can be designed to use either an internalLDOor an internalDCDC converter. The DCDC converter provides better current savings and will be used in most modules. If there are problems to get the SX126x to work, check which HW configuration is used and setUSE...

This Processing sketch creates a file (using the current date and time as the filename) in the same directory as the Processing sketch. Messages received from Arduino are added to the file. Pressing any key saves the file and exits the program: /* * ReceiveMultipleFieldsBinaryToFile_P * ...
Looking at the image we get a sense of what happens. Signal 1 surpasses the threshold and activates the sweep; signal 2 is inside the sweep time and gets caught with the first; after the holdoff, signal 3 activates the sweep again; ...
