how i force sequence pier slight wait line pristine before eventuality the data?

here's credentials i'm perplexing do:

1. open sequence pier mobile device bluetooth printer.


2. send an epl/2 form bluetooth printer, understands provide information receive.


3. once form received, send information printer printed tag stock.


4. repeat step 3 times required any tag printed.

step 2 wholly happens initial time, given form does need communicate any label. emanate i send form, i send tag information too fast print. infrequently i "bluetooth failure: radio non-operational" printed tag instead information i sent.

i have found proceed around emanate doing following:

for (int try = 0; try < 3; attempt++)
{
    try
    {
        serialport.write(labeldata);
        break;
    }
    locate (timeoutexception ex)
    {
        // record info arrangement info formed ex.message
        thread.sleep(3000);
    }
}

so basically, i locate timeoutexception retry slight after sharp certain volume (three seconds seems work time, nonetheless any reduction seems pitch difference each attempt). after 3 attempts i only assume sequence pier something wrong let user know.

this proceed seems work ok, nonetheless i'm certain there's improved proceed hoop this. there few properties serialport category i cruise i need use, nonetheless i can't unequivocally any good support examples them. i've attempted enactment around properties, nonetheless zero seem i'm perplexing achieve.

here's list properties i have played with:

• cdholding


• ctsholding


• dsrholding


• dtrenable


• handshake


• rtsenable

i'm certain multiple hoop i'm perplexing some-more gracefully.

i'm controlling c# (2.0 framework), zebra ql 220+ bluetooth printer windows mobile 6 handheld device, creates any inadequacy solutions.

any suggestions appreciated.

[update]

i should also note mobile device controlling bluetooth 2.0, since printer wholly during chronicle 1.1. i'm presumption speed inadequacy what's causing printer loaf behind receiving data.
