Okey, I didn't know that the BLE sensor is an Android tablet.

In that case I would think that you should do normal GATT and then has some proprietary code on the proxy node to convert (and cache) GATT messages from and to the BLE sensor.

The BLE sensor is an Android tablet and hasn't got the ability to act as an LPN node, well, at least there's no software that I can find to make this happen. I also want to avoid changing the Android tablet as it can be communicated legitimately without the mesh network i.e. from another phone or tablet.

Perhaps I should treat the BLE sensor as per any other peripheral attached to my nRF52840 node i.e. have the node provide a dynamic set of services, even of the same type, in relation to the number of BLE sensors it can find... Do you see any problems with taking such an approach?

Hi Christopher,

What you described is more likely the feature for Friend and Low Power Node (LPN) not for proxy and GATT device.

There is no caching when doing Proxy.

I would suggest to make the BLE sensor works as LPN node and if you need GATT it can do GATT in addition to LPN mesh role.
