52811 BLE and indoor direction finding

[Daniel168999]

Does nFR5811 support the BLE?    

Does nFR5811 support the Bluetooth5 and zigbee?    

nFR5811 have Accurate positioning with the world's most popular wireless technology. how is Penetration of nFR5811？ Can it’ signal penetrate the table？

Yes - but nRF51 are not recommended for new BLE development:

Is that a question?

It's not about the particular chip - it's about the laws of physics and radio propagation

depends on what the table is made of, how thick it is, etc, etc, ...

again, standard RF propagation stuff - nothing to do with the particular chip.

Sorry:  If "5811" is supposed to mean "nRF52811", then it does support BLE 5 .

You can read all that in the Product Specification:

But note that there is currently no software support, nor development hardware for the direction finding stuff - search the forum (using correct part number) for many posts on the topic...
