UARTE Frame error receiving

[Thomas]

Hi

I am seing framing errors when receiving using UARTE.

It is not external hardware, I have checked with different other interfaces and measured timing, no problems there.

BUT, doing the same with UART instead of UARTE I do not get any framing errors (same hardware setup).

Actually with UARTE I only get one rx character then framing errors....

Exactly I need to process data as it arrives and do not know the count in advance.

But are there any documentation available? I do not find anything not even a few lines describing what it is capable of and what the limitations are...

I have not seen this library before, but this must be the 6 and 7 uart sdk libraries available

Hi Thomas,

SDK 16 (which was just released) has documentation for libuarte. There are also two examples:

• Libuarte Example
• Libuarte Command Line Interface (CLI) Example

The library exist in SDK 15.x as well, but with less documentation and experimental examples.

Can't use SDK 16 as I am using Keil uVision Professional and some required device pack is missing and seems unavailable. NordicSemiconductor.nRF_DeviceFamilyPack_NordicLicense.8.27.0

Hi,

I see. The device family pack version 8.27 is not available in the pack installer yet, but you can download it from here by selecting it in the dropdown on the left. If you are starting now, I recommend going for SDK 16, but the libuarte library is also available in SDK 15.3.

Thanks - It seems there are multible locations for download, the one I found looked different and had latest 8.26.

I am not starting now but modifiying an existing project from using one uart to using two uarts. And that had shown to be very difficult.

Will SDK 16 require a SoftDevice update in my targets?
