Hi,
The function com_getAssociationView is supposed to read from the file if it exists, else read from meter and save to file. But it is not saving to the file even though 58 objects were read from the meter. Upon inspecting I found that CURRENT_ASSOCIATION[0] is null. Please let me know how to save to the file.
Sample code:
int ret = com_open(&con, port);
if (ret == 0) {
//Initialize connection.
if ((ret = com_initializeOpticalHead(&con)) != 0 || (ret =
com_updateInvocationCounter(&con, invocationCounter)) != 0
|| (ret = com_initializeOpticalHead(&con)) != 0 || (ret =
com_initializeConnection(&con)) != 0 || (ret =
com_readAllObjects(&con, outputFile)) != 0) {
printf("connection failed: %d\r\n", ret);
} else {
printf("connected ...\r\n");
while (1) {
bool result;
uint16_t volt = getVoltage(&result);
printf("volt: %d\r\n", volt);
sleep(2);
}
}
}

There is some problem with
There is some problem with com_readAllObjects() call while reading extended registers. So I am not using com_readAllObjects(). It means you can't use oa_findByLN(). I directly use com_read(). For example:
unsigned char ln[] = { 1,0,32,7,0,255 };
gxRegister regObj;
INIT_OBJECT(regObj, DLMS_OBJECT_TYPE_REGISTER, ln);
int ret = com_read(&con, ®Obj->base, 2);
if (ret == DLMS_ERROR_CODE_OK) {
} else {
}
