After using hc-05 to connect to my android, does the job - but I would like longer range. So I bought hm-10 "ble 4.0", because I thought it had a longer range. Not sure if it actually does since it's taken me a very long time to figure out the android part of connecting to it. So far, when I was able to connect ble to the hm-10 the range seemed to be about the same as hc-05.
Has anyone used any other modules to get an extended range with bluetooth? The application I'm building is for car/automotive, and connects to Android (via bluetooth). Blindly buying modules and testing them gets expensive in budget and especially my time and effort. So I figured I'd ask if anyone actually has experience with specific hardware known to work, please.
