11.0 Software Features and Functions
11.1 Radio Module Firmware
Radio module firmware running on the Radio module microcontroller (MCU) communicates
with the host, controls all aspects of the radio chipsets, RF front end and Tx/Rx switch.
11.2 Radio module serial number storage
During manufacturing, radio module serial number and part number are stored into the radio
module MCU write-once non-volatile flash memory. This allows host to query radio module part
number and serial number and therefore allow correlation of each radio module with the factory
test report.
11.3 Radio Type storage and security
RA1202 radio module has 2 hardware types. These 2 hardware types are configured during
manufacturing into 12 different radio types to meet country region approval requirements. Radio
type is factory set and stored in the radio MCU non-volatile memory.
Radio type is locked outside of manufacturing of the radio module. There are 3 levels of security
to ensure end users cannot modify the radio type outside of factory or authorized service depots:
