4.3 Software migration
For an overall description of the module software operation please refer to the u-blox 7 Receiver
Description including Protocol Specification [4].
4.3.1 Software compatibility
u-blox 7 modules introduce a new firmware: Version 1.00. When migrating, customers should ensure that
commands used originally with u-blox 6 products are supported by the new firmware version. For information
about known limitations that could affect migration, see the u-blox 7 Firmware Version 1.0 Release Note [5].
Table 17 provides a summary of important software migration issues to note.
Changes The configuration of the Tx-Ready feature has changed between MAX-6 and MAX-7 modules and is only recognized from
LEON FW 07.70 and LISA-U2 01S onwards. The MAX-6 TxD pin is mapped to PIO#5 while the MAX-7 TxD pin is mapped
to PIO#6. When communicating with u-blox wireless modules, this change of pins is not recognized by LEON FW7.60.02
and previous versions.
u-blox 6: 0 s leap second by default FW 6.02 and FW7.0x: 15 s leap second by default
u-blox 7: 16 s leap second by default
Table 17: Summary of important software migration issues
Low power modes are supported by the Power Save Mode of FW 1.0 or ROM 1.0. For migration consult
the u-blox 7 Firmware Version 1.0 Release Note [5] and the u-blox 7 Receiver Description Including
Protocol Specification [4].
