Hello Vasile and Rob,
Thank you for your feedback.
@Vasile;
1 - No. It will depend on the number of SMS received by the modem. But only
need the 2nd line of each SMS. This answers your #2.
2 - Yes. But this is still a test information received as an SMS. Later on,
it will be different and much probably bigger in nr of chars...
@Rob
Am not sure on how to use that and copy the data from the buffer to a large
array library.
Maybe some sample code would help.
Heres my receiving code, anyways:
for 50 using Index loop
fRtn = serial_hw_read(char)
if fRtn then
Received[Index] = char
end if
end loop
--
fRtn=FALSE
--
for 74 using Index loop
if (Received[Index]=="+"
& Received[Index+1]=="C"
& Received[Index+2]=="M"
& Received[Index+3]=="G"
& Received[Index+4]=="L"
& Received[Index+5]==":") then
fRtn=TRUE
end if
end loop
Thank you guys for your help.
Cheers,
FS
