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........?
