Hello,
I am currently working on a project using the NRF9160DK and I am encountering an issue when trying to add another UART (UART3) to the BLE NUS example.
I have successfully managed to use the hci_lpuart for BLE communication and can run the BLE NUS sample. However, for my use case, I need to add UART3 to my project.
The problem arises when initializing UART3 and trying to assign a callback function for it. I receive the following error on RTT: <err> peripheral_uart: Cannot initialize UART callback.
Here is my overlay:
And relevant code for uart3 initialization:
Any guidance on how to resolve this issue would be greatly appreciated.
Thank you in advance for your help.
Best regards, Vincent
