if nRF52840 is central how many peripherals can be connected at the same time using BLE 5.0 long range

[weightwatcherphil]

I am using SDK15 and S140 and nRF52840 as central.  I plan on deploying a lot of temperature sensors each of which will

have a nRF52840 acting as a peripheral also using SDK15 and S140.  I want to know how many peripherals (temperature sensors) can be paired with the nRF52840 acting as central.

I plan on using BLE  long range.

thanks
