DDS mirco IP address on Embedded Board

Hi all,

I hope someone here can help me, been looking a lot through the documentation and I can't seem to figure out what I'm missing.

I have been trying to get RTI Connext DDS Micro (2.4.14) to work on a microcontroller, the Nucleo-H745ZI-Q.

The furthest I have now gotton is that i was able to create a data reader that is visible in the RTI Administration Console (see attachment). But as you can see there is no IP address or locators data, which makes it that the microcontroller can't receive packages.

DDS Micro 2.4.14 exchange monitoring

Hello,

 

We are using the DDS Micro 2.4.14 alongside the AUTOSAR SW, We have communication with other peer.

We need to monitor the data exchanged, So my question is, Is there something like the RTI launcher dor the DDS Micro 2.4.14

Compileing DDS Micro to ESP32

Hello,

I'm trying to complie DDS Micro for ESP32, firstly just to run some kind of Hello World. My dev. board has 2MB of flash memory, that should be enough.

I'm planning to use it with the ESP32 SDK (if possible..), that is based on a modified FreeRTOS and an lwIP stack. (https://www.espressif.com/en/products/software/esp-sdk/overview)

What means this error message: ModuleID=6 Errcode=59

Hello,

This is with  DDS Micro 2.4.11

I have this following error message:

Problem with recording of large data packets (~8MB) from DDS Micro

Hi,

we have a problem while recording large data packets (~8MB) with the DDS recording service.

Our goal is to capture some sensor outputs (gps, radar, camera,...) to later make an offline stimulation of our DDS Micro 3.0.0 nodes with the DDS replayer service.

Therefore we have some gateway (DDS Micro), that is converting the raw senormassages from ROS format to DDS format and then this raw DDS data packets we want to record.

Can we dynamically create and free data writer?

Hi,

Currently, all data writers are created before use and that consumes memory. Some topics (and thus data writers) are events that only be invoked under certain scenarios, and can be created when necessary and release after used.

Is there a way to support dynamic creation and release of data writers, just like malloc() and free() ?

_udp and lwip for DDS Micro

Hi,

I have developed a simple DDS Micro application. One installed in my labtop running Windows, another into my ARM STM32F469 micro-controller. For the laptop, the transport uses the built-in _udp and the embedded used the lwip. Both were tested using the Admin Console. Here are some observations.

IDL converts sequence<> to struct?

Hi,

 

I have a question of using sequence. I added in seqence in IDL, for example below:

struct myTestSequence_T {

double myFirstVar; //@key

seqence<long,10> mySeqLong;

};

After convertion to C using rtiddsgen, the sequence was translated to struct. See below. 

typedef struct myTestSequence_T{

CDR_double myFirstVar;

struct CDR_LongSeq seqLong;
