Software

All software information to use the GW16122-B and newer should be found on the Gateworks CC135x wiki page. This is because the CC135x chip is used on many designs.

The GW16122 revision B and onwards uses the TI CC1352P chip. (GW16222 revision A used the CC1350 chip. )

The typical OS used is Ubuntu. Various different firmwares exist for the CC1352 chip, but the default loaded firmware is a slightly modified version of the EasylinkNp firmware. This firmware is described in more detail on the software page listed below.
