2 .3 Signal test
Five LED’s have been mounted on the GSM7i module to indicate the current
GSM signal strength.
Immediately after starting up the module, it will try to connect to the GSM
network, and the signal strength indicator will be activated (see paragraph 2.4,
page 11).
If a higher resolution of the signal strength is required, it is possible to make a
signal test with the test button:
1. Press the button for 2 secs. after which the test diode
turns on and lights for approx. 10 secs.
2. The test diode will now indicate the signal strength
with flashes.
One long flash equals 10 and a short flash equals 1.
E.g.: Two long flashes and three short flashes equal a signal
strength of 23.
See paragraph 2.4 “Diagram of signal conversion”, page 11 for
more details.
