Thank you, this looks legit, let me run tests Please update commit message, to explain what was the observed issue and the motivation of the fix (reference to specs will be also appreciated) Reviewers welcome (I cant add names) cc: @lmolina @ochavezmiranda @Thomasdjb @XavierPerraud-Silabs |

I noticed an issue (not related to this change) in build log: 1046.6 Generating codsh: 1: mscgen: not found https://en.wikipedia.org/wiki/MscGen May this be fixed |

I would recommend something closer to the source code of the Z-Wave stack:
uint8_t index = (subcmd - 1) / 8 + 1; // +1 because the sub command bitmask start at index 1 instead of 0.
uint8_t mask = (1 << ((x - 1) % 8));
return capabilities.supported_serialapi_bitmask[index] & mask;

Why subcmd is limited to 16?
Highest subcmd defined in the controller is 22: SERIAL_API_SETUP_CMD_GET_REGION_INFO.

I believe the reason is the limitation of the Z/IP Gateway, which only supports a few specific Serial API subcommands.
The Z/IP Gateway supports only the following Serial API subcommands:
SERIAL_API_SETUP_CMD_UNSUPPORTED,
SERIAL_API_SETUP_CMD_SUPPORTED = 1<<0,
SERIAL_API_SETUP_CMD_TX_STATUS_REPORT = 1<<1,
SERIAL_API_SETUP_CMD_MAX_LR_TX_PWR_SET = 3,
SERIAL_API_SETUP_CMD_TX_POWERLEVEL_SET = 1<<2,
SERIAL_API_SETUP_CMD_MAX_LR_TX_PWR_GET = 5,
SERIAL_API_SETUP_CMD_TX_POWERLEVEL_GET = 1<<3,
// SERIAL_API_SETUP_CMD_TX_GET_MAX_PAYLOAD_SIZE = 1<<4,
SERIAL_API_SETUP_CMD_RF_REGION_GET = 1<<5,
SERIAL_API_SETUP_CMD_RF_REGION_SET = 1<<6,
SERIAL_API_SETUP_CMD_NODEID_BASETYPE_SET = 1<<7,

Can this change be merged in? We needed this change when using the latest zipgateway. FYI @lmolina |

This PR fixes an issue in SupportsSerialAPISetup_func() where the subcommand ID was incorrectly used as a bit index in is_bit_num_set_in_byte(). This prevented MaxLRTxPowerLevel from being configured via zipgateway.cfg.
