Nrf 52833 ble aoa application

[Ronnie]

Hello Guys

I'm currently working on a BLE AoA (Angle of Arrival) application using the nRF52833 Development Kit. I’ve run into some challenges regarding hardware connectivity and was hoping you could provide some guidance.

The J1 connector on the dev kit needs a Murata MXHS83QE3000 cable, and based on my research, it seems to be one of the few compatible options for interfacing with the dev kit. However, when attempting to connect this to my CoreHW antenna array, I discovered that I need a custom converter PCB to bridge the two coaxial interfaces. This compatibility issue is quite time-consuming to resolve, and I find it hard to believe there’s no more straightforward solution.

My questions:

1. Are there any standard components, adapters, or cables listed or recommended by Nordic for connecting external antenna arrays or AoA-compatible hardware to the nRF52833 dev kit?

2. Does Nordic Semiconductor have official partners that provide a reliable, ready-to-use solution for BLE AoA development using the nRF52833 DK?

Thanks

Hi

1. No, we don't have any specific standard coax cables or similar, most should do AFAIK, as long as it's not several meters long. The shorter, the more accurate and better it is generally.

2. Insight SiP is our partner for Bluetooth LE AOA kits, and you can check out the ISP1907 AOA DK available from their home page here: https://www.insightsip.com/products/bluetooth-le-modules/isp1907
