Hello,
I am in the process of integrating a project where I need 3 uarts to work concurrently in different configurations. This will eventually migrate to an application where the nrf52840 will also serve as a beacon.
I have individually proven I can talk to and control each of the 3 peripherals over UART by using the ..examples/peripheral/uart example in sdk 15.3. I am using the Segger development environment.
I was hoping it would be simple to migrate to controlling all three uart peripherals in a non-blocking mode using the serial_uartes example as a starting point. My objective is to also include handlers that will capture and parse each uart receive port.
However, I cannot get the basic serial_uartes example to work in the first place. I have read many of the other Devzone cases and do not see one that conclusively corrects the issue with the example.
One of my peripherals works in handshake mode the other 2 are asynchronous. I have also had some issues with getting handshake to function as expected (the nrf52840 must work as a DTE. Can you tell me if the Nordic implementation follows the "normal" set of rules as indicated below (except for the DTR) which I need to handle manually.
1.The data terminal equipment (DTE) puts the RTS line into the “On” state.
2.The data communications equipment (DCE) puts the CTS line into the “On” state.
3.The DTE puts the DTR line into the “On” state.
4.The DTR line remains in the “On” state while data is being transmitted.
I need to demo this capability to my customer as soon as possible since I have already been able to successfully talk to all three peripherals independently. I have spent more than a week attempting to resolve this issue.
Thank you in advance for the normally quick responses from your support team.
