Hello All,

I have been using UART1 without hardware or software flow control. What are the benefits to using software flow control and if I decide to do so, when should I be calling uart_set_rts() and uart_set_dts()?

Specifically, by logging a time value I'm reading that each polling transaction takes around 3 ms. Should it not be much quicker? <100 us?

I'm making consecutive calls to one device using polling transactions. I have acquired the bus in initialization. My transactions are relatively short and usually come in chunks of 10 (10 polling transactions).

I find that the speed is still not satisfactory. How can I improve this?

Thanks for the response. My concern about my original point is that I'm worried while the high priority task is processing the IRQ, the other core may be running a task that disrupts this tasks function by maybe using some shared resource or something. What I really would like to do is for have this...

Currently, program crashes if I try to do a spi_device_transmit.

I'm thinking about setting up a task with a very high priority and have the IRQ handlers send objects to a queue, which in turn wakes up the high priority task to do the processing. Are there any alternatives?

I've downloaded the arduino core as an esp-idf component. How do I make the arduino files build?

If the esp module loses connection to the router, then the disconnect is called.

If the router loses connection to the rest of the internet by removing the ethernet cord, then neither the wifi event handler nor the mqtt even handler indicates the connection has been lost.

When would this usually happen and what steps are necessary to take related to socket work?

Right now I'm shutting down sockets on a SYSTEM_EVENT_STA_DISCONNECTED. Is there a chance that the SYSTEM_EVENT_STA_LOST_IP event can trigger without SYSTEM_EVENT_STA_DISCONNECTED being triggered also?
