php - Teltonika FM1100 GSM device Avl Data Ack -

1) gps fm1100 module sends following data

imei
123456788927333

2) send 01 binary gps module ( imei no.accepted, tell module send raw data)

3) gps send below raw data

raw data

4) able parse data , send acknowledgement gps module

5) gps module keeps sending old data repeatedly in spite of send correct acknowledgement data.

we not sure whether sending acknowledgement data in correct format mentioned in gps module manual.

please on regard.

        if(strlen($rdata) == 15){            $this->imei = $rdata; // imei number gps module            $codata = pack("h*", "01"); // accept connection , tell gps module send data            $this->server->send('current client socket', $codata); //send gps module         }else{            $bh = bin2hex($rdata); // gps module rawdata bin hex            $sql = $this->sqlparsingfm($bh); // parsing data             $sdata = $data["norecord"]; // parsed data gps module. no of record received             $hex = str_pad($sdata, 8, "0", str_pad_left);            // $hex = "0x06";            // $hex = pack("h*", "0x06");             $this->server->send($e->parameters->idclient, $hex);         } 

?>

below gps module documentation link

page no 7. communication server section. sending response module

http://www.sourceforge.net/p/opengts/discussion/579834/thread/6fd0ffe8/6213/attachment/fmxxxx%20protocols%20v2.10.pdf

first, don't use pack when it's not necessary. so, replace:

$codata = pack("h*", "01"); // accept connection , tell gps module send data $this->server->send('current client socket', $codata); //send gps module 

with

$this->server->send('current client socket', "\x01"); 

next, send correct packet confirmation, change

$this->server->send($e->parameters->idclient, $hex); 

to

$this->server->send($e->parameters->idclient, pack('n', $sdata)); 

and should fix everything.
