BLE Configuration

Mr.NCK

HI

We have to try to develop a product with nrf5340. The product needs to be waterproof and also it made up of metal and a small amount of plastic enclosure. In that how much strong BLE communication I can make it and what is the maximum distance range I can reach out to. And also let me know what are procedures I need to follow to achieve long-range BLE communication.

Thanks & Regards

    Hi,

    It's difficult to give any exact answer here, because there are many unknown factors. If you submerge a BLE device in water, the range will be 0. There is no radio propagation through water. If you make a casing that is waterproof, that does not mean that the range will be impacted in a negative way by itself, but it's important that the product is tuned in the final casing to achieve the best performance in terms of output power and antenna impedance. This is something we can typically help you with, but you will need to share you schematic and layout with us for review before you manufacturer you board in such case. In general, typical range for a BLE device is around 10meters (but it will depend on the environment, for instance is there any walls or obstacles between the peers).
