2.1.4.5 OTA Firmware Update Procedures
The generic procedures defined in this section provide standardized methods of using the features of the OTA Service [1] in specified sequences in order to satisfy common use cases. This profile does not forbid the use of the features of OTAS in other ways and a higher layer profile may define such additional procedures. However, wherever a procedure listed in Table 4.4 is supported, the implementation of the procedure shall conform to the requirements of this profile specification.
The following diagram shows the message sequence chart of OTA firmware update process.
