Using STM32F030 R8 Nucleo Board
Using Ubuntu 20.04, ROS Noetic

I am also facing the same issue with STM32F303RE Nucleo board using Ubuntu 18.04, ROS Melodic.
Couldn't find a solution yet... Also, if I try to use rosserial_server I get "Socket asio error..." and I cannot see the topics that I'm supposed to be publishing from the microcontroller

@tahakenar @deepchand41
check the DMA settings, set the mode to normal and then have a try.
cheers!

it seems doesn't work :STM32F407+ubuntu20.04(notetic)

  • Only in rare cases does it work：

[INFO] [1683649672.768868]: Requesting topics...
[INFO] [1683649673.098597]: Note: publish buffer size is 512 bytes

  • Most of the time it reports an error like this and i don't know how to solve:

I encounter the same issues. Has it been solved now? I found that when the server sent a clock syn signal to the stm32 node, the usart of the node would be interrupted, causing that the message transmits incompletely which might be root of this problem.

But I have no any clear train of thought about it.
