Hi,
I'm currently involved in implementing the transmission of variable-length data within Zigbee clusters. While I've successfully managed operations related to the String data type, I'm encountering challenges with the struct data type. I would appreciate it if you could review the provided code snippets and offer suggestions or corrections to address this issue.
// ZCL_DATATYPE_STRING_CHARACTER - This snippet worked fine
uint8_t myData[17] = " 123456789876543";
static struct ZbZclAttrT ZbZclAttrElecMeasAppendList[] =
{
{ZCL_OWN_ATTRIBUTE,
ZCL_DATATYPE_STRING_CHARACTER,
ZCL_ATTR_FLAG_WRITABLE,
32,
NULL, {0, 0xffff}, {0, 0}},
};
ZbZclAttrStringWriteShort(zigbee_app_info.elec_meas_server, ZCL_OWN_ATTRIBUTE, myData);
Encountered 0x86 error when I tried to do the same on Struct data type. Below, #1 and #2 none of them were worked for me.
typedef struct {
uint8_t A;
uint16_t B;
uint16_t C;
uint16_t D;
uint8_t E;
uint32_t F;
} ZCL_MY_Attributes_t;
ZCL_MY_Attributes_t MY_SET = {0x01,
0x1234,
0x5678,
0xABCD,
0x00,
0xEFABCDEF
};
static struct ZbZclAttrT ZbZclAttrElecMeasAppendList[] =
{
{ZCL_OWN_ATTRIBUTE,
ZCL_DATATYPE_STRUCT,
ZCL_ATTR_FLAG_WRITABLE,
15,
NULL, {0, 0xffff}, {0, 0}},
};
// #1
//=====
ZbZclAttrStringWriteShort(zigbee_app_info.my_clus, ZCL_OWN_ATTRIBUTE, MY_SET);
// #2
// =====
ZbZclAttrWrite(zigbee_app_info.my_clus, NULL,
{ZCL_OWN_ATTRIBUTE, (const uint8_t *) MY_SET,
15, ZCL_ATTR_FLAG_WRITABLE);
I'm seeking guidance on how to properly write data for the ZCL_DATATYPE_STRUCT. If you could provide insights or suggestions on the process, it would be greatly appreciated.
