Hello Everyone
I had made a project to send sensor data from one device to another using hc-05 Bluetooth.
i had covered both transmitter and receiver in two different aluminum enclosure, but i faced problem in pairing the when enclosure was closed for both transmitter and receiver and kept at 7 meters range, devices were not pairing. then i removed removed device from enclosure then it got paired. so i thought signals are getting weak if i keep Bluetooth in enclosure.
can some please suggest me which type of Bluetooth i should use, it has to connect/pair with other at minimum range of 10meters.
I was also thinking to use Bluetooth with external antenna. so please suggest me the best solution and please correct me if i am wrong.
I saw HC-12 is good can someone who has used HC-12 for long range tell me how it worked and i can use for my project.
Thank you in advance
