dwm_dev_info_get

Gets the firmware ID, firmware version, configuration version, and hardware version of the module. Firmware ID has a default value 1 on the gateway and a default value 2 on DWM1001. Firmware with ID 0 on the gateway and firmware with ID 1 on the DWM1001 are used as possible backups. The backup firmware is used during firmware updates .

void dwm_dev_info_get(dwm_dev_info_t *info);

Parameters

output – Status code, fw_id, fw_bckp_version, fw_version, fw_bckp_cksum, fw_cksum, cfg_version, hw_version
fw_id – 32-bits integer ? (ID of a firmware that is currently active)
fw_bckp_version – 32-bits integer ? (maj, min, patch, res, var)
fw_version – 32-bits integer ? (maj, min, patch, res, var)
fw_bckp_cksum – 32-bits integer ?
fw_cksum – 32-bits integer ?
cfg_version – 32-bits integer ?
hw_version – 32-bits integer ?

C code example

dwm_dev_info_t info;
dwm_dev_info_get(&info);
printf(“FW ID=%d\n”, info.fw_id);
printf(“FW version: maj(%d) min(%d) patch(%d) res(%d) var(%d)\n”, info.fw_ver[1].maj, info.fw_ver[1].min, info.fw_ver[1].patch, info.fw_ver[1].res, info .fw_ver[1].var);
printf(“CFG version: x%08x\n”, info.cfg_ver);
printf(“HW version: x%08x\n”, info.hw_ver);
