Its possible to keep two SoC in same custom board for in and out logic

[Venkat RAM]

hai team, 

My requirement is to design a custom board as a sensor to identify the person who enters and exits the room based on an advertiser device

I had planned to create a custom board with two BLE SOCs, where, if the person (advertiser) crosses the sensor, based on the direction,

if advertisement data is read first on the first soc of the Custom board and next on the second soc on the same custom board which mounted on the wall

then I make an entry as IN

if advertisement data is read first on the second soc of the Custom board and next on the first  soc on the same custom board mounted on the wall

then entry as OUT

here the problem is  the antenna propagation of signal is 360  like given below

can i customise the nrf52840 soc's antenna like 

in case not applicable give me an idea based on my requirement

Note: here direction finding  soc of did not suit, because, at a moment, there are more advertisers will be crossed over the  sensor, connection concept was not suits 

only broadcaster and advertiser concepts suit

Hello Venkatraaman,

Sounds like an interesting project!

direction finding  soc of did not suit, because, at a moment, there are more advertisers will be crossed over the  sensor, connection concept was not suits 

only broadcaster and advertiser concepts suit

I am not sure if I am understanding what you mean here. Though I understand that direction finding might be a bit of an overkill for a situation like this.

I should mention that there are occupancy sensors etc available out there. Simply using a pair of them might be enough for your use case.

if advertisement data is read first on the first soc of the Custom board and next on the second soc on the same custom board which mounted on the wall

If you want to pursue this line of thinking I think you might want to try out our distance toolbox. Have a look at this webinar for further details.

Thank the reply 

"I should mention that there are occupancy sensors etc available out there. Simply using a pair of them might be enough for your use case."

plz mention the sensor name and in-want method, I can find the in and out logic.

customizing the nrf52840 soc's antenna is not needed for my requirement right?

I can't give any particular recommendations but I'm sure you'll find a lot by simply google'ing.

I'm not sure if I understand. That depends on what you want to create.
