I'm not sure that this is correct

offset size type description
0x04 2 offset ? value 0x489 (for running.fw 0x4a1). After jump to the offset 48 80 47 0a (running: 48 80 47 15)
0x40 2 size length of data - it starts after CRC??
0x64 2 size? some size?
0x304 32 text device/processor name; filled with 0x0
0x37E ? text always? RW-BLE
0x39A 32? text name of BT device
0x420 6 value version (in running.fw is text, 8b?)
0x438 8 value probably some CRC32 value. (In running.fw is filled with 0xFF)
0x440 X data header? memory data...?

Mili_hr.fw
