Prototype a BLE and LTE using nRF5340 DK and/or nRF9151 (or 9161) DK

[lcj]

I have both a nRF5430DK and a nRF9151DK (or 9161). If I wanted to develop a solution with both BLE and LTE, how do I set up a DK environment for them to work together? Do I chain the DKs or something?

This is up to you how you want the two devices to communicate, but you will need to connect some pins together.

You can look at our nRF9160DK or the Thingy91 as examples as these to devices have both a LTE and a BLE chip on the same PCB. You can use the Asset Tracker v2 as a guide as well to how communication is set up between the two.

But in short, you can set up communication over UART between the two DK's, and if needed you can use some co-existence features If that would be relevant.

Can I pool the RAM between the two and do you have examples of how to do that?

No, RAM can not be shared between to devices in such a way.
