Hello,
We want our device (STM32-F446RE running FreeRTOS + Telit ME310G1 modem) to communicate to the AWS cloud. We are trying to follow the Cellular Interface Library Demo, in particular following the diagram
We are using coreMQTT Agent, MbedTLS libraries, the amazon communication interface implementation for UART, and amazon UART API implementation (I was unable to add the links).
UART using 115200 baud rate.
Currently failing on the Cellular_Init function when trying to send the first AT command to the modem, specifically when calling the HAL_UART_TRANSMIT_IT function from the above comm interface send function. While debugging we see that the USART1_IRQHandler is called infinite times and nothing is sent through the UART communication.
We are using the default handler, do we need to implement it in any way?
void USART1_IRQHandler(void)
{
HAL_UART_IRQHandler(&huart1);
}
Any help will be appreciated.
Thanks in advance,
Guy
