best ble............?

[iqbalpalemad]

Hai

i am planning to make an iot project with ble for my academics. I am using arduino to control the ble. I was done a test with blend micro to know its maximum range of communication but it was too shorter than i expected.it was just 14M in Line Of Sight .I need at least 100 feet range. So i would like to know the factors affecting range of ble and how can i improve the range of a ble devidce.............?

Can anyone suggest me any ble device with a range of at least 100feet in line of sight........?

thank you

Note that for 2-way communication, higher transmitting power from one side is not enough, you need high output power from the phone also. I can't say the nRF5 series at 4dBm would guarantee communication with your phone at 30m since I have no data about your phone also it depends on the environment.

In the future (2017), with Bluetooth 5.0 release and long range feature, 1-200m will be possible.
