Foarte bun

L-am testat in comunicatie seriala la 9600 - 115200. Merge foarte bine, nu chiar 1 Km dar am reusit rezultate bunicele la 300-400m in camp deschis.

Excelent

Cred ca este evident pentru toata lumea ca distanta de 1 KM poate fi atinsa doar in aer liber si fara sa existe obstacole.
Am cumparat 2 bucati, am lipit pinii si antena cu care a venit si am testat partea de transmitere/citire. Functioneaza aproximativ 100m. Un modul era in casa la etajul 1 iar pe celalalt l-am dus cu masina 100m (pentru ca ploua afara am mers cu masina cei 100m).
In casa am testat intre etaje cu unul din module inchis intr-un dulap cu cos din bare metalice (care pot ecrana semnalul) dar a functionat si asa.
Din ceva motive necunoscute cand am incercat sa-l pun in modul FU4 (pentru range maxim), dupa comanta AT+FU4 nu am mai putut comunica cu el nici la 1200 BAUD rate nici la 9600 sau alte variatiuni. Am rezolvat comunicarea punand pinul de SET la GND inainte de a alimenta modulul cu curent - astfel modulul trece implicit pe 9600 BAUD rate. Oricum aceste detalii se gasesc in manual...
