Problem with hserin wait

Hi everyone, it is possible to wait 3 characters with the wait with this syntax ?

HSerIn 1000,imp_numeri,[Wait("OK",13,10)]

Thank you

yes.. the sample below is from a SIM900A routine I always use.

HSerIn 300,TIMEOUT,[Wait(CR,CR,LF),Str GlobalBuffer]

yours are waiting for 4 characters.

Giuseppe

Thanks Sweets for replying to me. In fact I was working with an 800 SIM. I wanted to create a system with 5 numbers stored in the white list with 3 rings to activate an exit and have confirmation with another 3 rings. Do you happen to have a list ready?

Giuseppe

when sending the command
HSerOut ["AT+CPBR=",Dec i,44,Dec i,13] to read the numbers stored in the sim. If there are no numbers the answer will be:
CR LF OK CR LF while if there are numbers the response will be:
+CPBR: 1,"3405211233",129,"Daniel" (EX).
So how do you use wait for two different responses?

Dolci

acknowledge only one.
if the reply is CR LF OK CR LF then ignore it (meaning no numbers on that address)

what is the exact reply of sim800 if you send HSerOut ["AT+CPBR=",Dec i,44,Dec i,13] and a number is stored on that location?

Giuseppe

The correct answer to the question HSerOut ["AT+CPBR=",Dec i,44,Dec i,13] is +CPBR: 1,"3405211233",129,"Daniel" .
Now I'm trying to receive via buffered interrupt

Hi everyone, I'm trying to use an 800 sim module. I have no problems with Proc setsim800. The problem comes when I wait
HSerIn 500,imp_numbers,[Wait(0D,0A),Str rxbuffer] . In fact it keeps sending me back to imp_numeri, how to solve it?

I wonder if
HSerIn 500,imp_numbers,[Wait(0D,0A),Str rxbuffer] can receive several bytes of a byte array ?

Giuseppe

I also tried this waiting for the CP characters.
HSerIn 500,imp_numeri,[Wait("CP"),Str rxbuffer] I didn't solve the same
But it doesn't find them even if the analyzer sends them from the module
rxbuffer is 64 bytes, the string I receive is shorter, can it create problems?

Giuseppe

this is an example of a string that I need to receive  : CRLF+CPBR: 1,"3405310231",129,"Giuseppe"
