vb.net - Meitrack device what to return to confirm server recived data -

-

i communicating meitrack odb device, can receive data when set protocol to"event report needs servers confiramtion " , field (i resume cache count". in documentation can find "aff" return device, doesnt seem clear cache though.

***deleting gprs event in cache zone – aff gprs setting aff, number of deleted gprs events gprs responding aff, number of remaining caches,command type, (-) latitude,(-) longitude,data and

time,status,number of satellites,gsm signal status,speed,direction,horizontal positioning accuracy,altitude,mileage,run time,base station information,i/o port

status,analog input value description number of deleted gprs events: hexadecimal string. default value 1. number of remaining caches: total number of events in internal flash memory. hexadecimal string. applicable model example gprs sending @@h27,353358017784062,aff,1*0b\r\n gprs receiving $$h28,353358017784062,aff,ok*3d\r\n

you can not communicate device on tcp/udp . device ip , port not static or stable . changing mean dynamic . if want send command device have send sms . far figure out.
