Recently, I’ve been playing a bit with the SX126x transceivers. By dumping all of the registers, I found some useful and seemingly undocumented information. For example, at the address 0x0320 - 0x032F, there seems to be some device ID and possibly a revision string:
0000320 53 58 31 32 36 31 20 56 32 44 20 32 44 30 32 00 | SX1261 V2D 2D02.
Is it correct to assume that this is indeed the device type (“SX1261”) followed by some revision (“V2D 2D02”)? And if so, is this format documented somewhere?
More generally, would it be possible to publish some register map, as it was done on SX127x? I understand that some (or most) of the register contain some testing functionality which may not be published. However, the example above is something I was missing quite a lot on the SX126x, whereas on SX127x, this was as easy as reading a device ID register. I imagine there could also be more useful stuff in the registers.
