@NeverDie I have noticed that in the latest version of your adapter you have lowered the capacitor value used for the first stage filtering from 100uF to 10uF, leaving the second stage one to 0.1uF. Did you have empirical benefit in tests with this configuration? 0.1uF it seems to me at first glance too small to accommodate current draw fluctuation of this module. Would be appreciated if you explain your design choice. Thank you.

2.4GHz LoRa modules offer a good data rate compared to lower frequency ones that are very limited on this aspect, but they suffer path loss much more and wide use of 2.4GHz increase interference problem a lot.
I'm interested to know how they perform in typical urban use scenarios.
Has someone tested E28-2G4M27S in urban environment?
I have found only test result of people in very good condition as line of sight with no buildings or other obstacle interposed or at very short range (from a room to another in same building).
