I am attempting to add a UART to interface to an external MCU. I have the uart example running (without any RTT info) yet when I port the uart code to the ble-thread example I am not getting any data out the TX pin, I am getting data from the RX pin. What am I missing? Is the RTT messing with the transmitting of UART data?
I am helping Mike work on this problem. I followed Mike's guidance and created a project that matched his and duplicated the hard fault. But then I wondered if I could debug the "ble_thread_dyn_hrs_coap_freertos" example that Mike is using as his starting point and this project without modification also Hard Faults when I attempt to debug it. So, it appears to have nothing to do with the addition of the UART. At least the Hard Faulting doesn't.
I'm looking at the UART code separately, but am confounded that the example cannot be debugged.
I tried a couple more multiprotocol examples. Is this related to debugging with the soft device running?
I tested the UART code in isolation and it appears to work just fine. I don't see a functional problem with it.
Does this have anything to do with this thread:
https://devzone.nordicsemi.com/f/nordic-q-a/45065/thread-networking-in-nrf52840-dongle
Which leads to this file:
which is a precompiled part of the Thread stack which may directly interfere with what Mike is attempting here?
Is UART0 taken always by the Thread stack? Should we then use UART1 and to use UART1, use the Serial driver?
matt.heins said:Is UART0 taken always by the Thread stack? Should we then use UART1 and to use UART1, use the Serial driver?
Good catch Matthew. UART0 is reserved by thread, here is more info on this
Hi TawMater,
I had some conversation with Matthew Adam, Andre Harris from the Nordic US team yesterday.
I started looking into an email you shared with them few days ago regarding trying to reproduce the URAT issue you have. I managed to reproduce it. And I came pretty close to have a project for you. Even though I see that the TX line is still getting corrupted, I suspect it is a configuration issue now rather than architecture.
I have made many changes to the hrs_dyn_coap_freertos example-
I will be leaving home for the weekend soon and thought to update you.with my current status of the project.
I am attaching the local copy of the project.

You need to replace nrf_log_frontend.c in your project with the one i attached.
I have modified the app that it sends all the received bytes to TX when it receives '\r'.
I am quite confident that I will fix the corrupt TX problem on Monday. Just letting you know the status so that you do not loose hope. We are pretty close to fixing this..
