Mobiltelefon

Vid f¨ors¨ok med mobiltelefon har det visat sig att n¨ar USART:en ¨ar avst¨angd ¨ar det viktigt att se till att TX ¨ar l˚ag d˚a i annat fall VPPFLASH effektivt styrs till h¨og, vilket resulterar i att mobiltelefonen l˚aser sig. Om TX ¨ar l˚ag en kort sekund, startas bara mobiltelefonen om men i annat fall l˚aser den sig “h˚art”. Det enda som upph¨aver denna h˚arda l˚asning ¨ar att avl¨agsna batteriet. Vid v¨antan p˚a synkroniserings-puls fr˚an telefonen befinner sig programmet i ett tillst˚and kallat SYNC. Det som sker i detta tillst˚and ¨ar att s˚a fort pin- nen som delas med RX g˚ar l˚ag kommer en mjukvarutimer, som g˚ar med frekvensen 1 kHz, att startas och r¨akna ned ifr˚an 10. Om RX pinnen skulle g˚a h¨og n˚agon g˚ang under den tid det tar f¨or timern att r¨akna ut kommer timern att startas om och ˚ater b¨orja r¨akna ned fr˚an 10. Talet 10 kommer fr˚an det att pulsen skall vara 10 ms l˚ang. Om timern skulle r¨akna ut g˚ar pro- grammet vidare till tillst˚and INIT i vilket initieringen av kommunikationen sker. Fl¨odesschemat i figur 11 beskriver synkroniserings-f¨orloppet grafiskt. Initieringsrutinen ¨ar beskriven i detalj i sektion 3.2.6.

N¨ar initieringen och identifieringen av tillbeh¨oret ¨ar utf¨ort g˚ar programmet vidare in i tillst˚andet IDLE. I detta tillst˚and ligger mikroprocessorn och v¨an- tar p˚a de sm˚a “handskaknings”-paketen som telefonen skickar med ca 5 ms intervall. Mikroprocessorn kommer att besvara majoriteten av dessa med ett “handskaknings”-svar. Om ett ID mottagits fr˚an RFID-l¨asaren kommer ist¨al- let denna data att skickas i ett SMS. ID:t blir d˚a representerat i hexadecimal form.

F¨ors¨ok med ett par olika AT-kommandon har utf¨orts, bland annat med AT*EAPP samt AT+CMGS. AT-kommandot AT*EAPP skall, enligt datablad[5], bland annat kunna skicka SMS och skriva notiser, men vid f¨or- s¨ok visade det sig att inga SMS kom fram skickade med detta kommando. Det g˚ar dock att anv¨anda kommandot f¨or att skapa notiser i mobiltelefonen s˚a som databladet beskriver. Det verkar s˚aledes troligt att det ¨ar en begr¨ansning i den mobiltelefon som anv¨ands vid dessa f¨ors¨ok.

Ytterligare Internets¨okningar p˚avisade att AT+CMGS ¨ar r¨att v¨ag att g˚a. Det finns bland annat ett exempel p˚a hur en person anv¨ander kommandot i Visual Basic f¨or att skicka SMS. Det visade sig dock att denna syntax inte ¨ar giltig i den mobiltelefon som anv¨ands, utan att denna anv¨ander en n˚agot annorlunda syntax. R¨att syntax, enligt databladet, ¨ar

AT+CMGS=<length><CR><pdu><ESC>

med f¨orklaringen att “length” avser antalet oktetter i PDU efter “Service Center Address” f¨alten. Vid s¨okningen fanns ¨aven ett dokument (se bilaga B), vilket beskriver hur ett SMS skickas med PDU fr˚an Siemens samt en Java-klass vid namn smslib. Studie av smslib samt exemplet p˚a sidan 31 i Siemens datablad visar hur ett PDU block skall skapas. F¨or ytterligare infor- mation om PDU, se sektion 2.4.1. F¨or att underl¨atta implementering har en fast str¨ang med plats f¨or 10 SMS-tecken valts samt 8-bitars teckenkodning. D˚a str¨angl¨angden h˚alls konstant inneb¨ar detta att enbart “User Data”-delen i PDU-str¨angen beh¨over bytas ut. S˚aledes ¨ar implementeringen i mikroproces- sorn t¨amligen enkel. Eftersom hela PDU-str¨angen sparas i RAM underl¨attar detta f¨or fels¨okning d˚a det enkelt g˚ar att s¨atta en brytpunkt i AVR Studio direkt efter att str¨angen skapats vilket medf¨or att verifiering av giltigheten host PDU:n l¨att kan g¨oras.

F¨or att skicka PDU-str¨angen till mobiltelefonen beh¨over PDU-str¨angen delas upp i ett flertal segment. Detta beror p˚a att varje paket som telefonen kan ta emot via den seriella l¨anken, enbart kan innefatta maximalt 15 tecken s˚a som beskrivet i sektion 3.2.5. Detta medf¨or att det kommer att ta ett antal “handskakningar” f¨or att ¨overf¨ora informationen till mobiltelefonen.

3.3.3 Sammanfogning av mobiltelefon och RFID-l¨asare

D˚a b˚ade generering av PDU-str¨ang f¨or SMS samt inl¨asningen av RFID- informationen sker helt separerat torde det vara relativt enkelt att sammafoga

dessa tv˚a funktionaliteter. Rent praktiskt kopieras de tv˚a kodblocken till ett och samma projekt. D˚a Wiegand 44 anv¨ander tv˚a egna avbrottsrutiner ¨ar det enklast att flytta ¨over dessa till mobiltelefon-koden. N¨ar sammanslagningen ¨ar utf¨ord ¨ar det bara att initiera avbrottsrutinerna samt st¨alla in- respektive ut-g˚angar. D¨arefter ¨ar produkten f¨ardig f¨or testning.

Resultat

Arbetet med den mobila RFID-l¨asaren resulterade i ett program skrivet f¨or en mikroprocessor av typ Atmel ATmega16. Programmet hanterar protokol- let Wiegand 44, vilket finns beskrivet i sektion 2.4.2, f¨or inh¨amtning av ID:t fr˚an mikrokontrola’s RFID-l¨asare TRD-HOT COMBO. Processorn anv¨an- der ¨aven USART f¨or kommunikation med mobiltelefonen av m¨arket Sony Ericsson. Kommunikationen med telefonen sker genom att AT-kommandon skickas inkapslade i ett bin¨art protokoll, vilket Sony Ericsson valt att h˚alla hemligt.

Programmet uppfyller de krav som f¨oretaget hade, d˚a det klarar av att l¨asa av en tagg och rapportera ID:t, fr˚an taggen, till en mobiltelefon med hj¨alp av ett SMS.

5 SLUTSATS OCH DISKUSSION

Slutsats och diskussion

Som slutsats kan dras att arbetet i vissa avseenden varit sv˚arare ¨an f¨orv¨antat, medan i andra avseenden har det varit enklare. Till exempel var jag inte beredd p˚a att ett SMS skulle vara s˚a sv˚art att skicka och kr¨ava s˚a mycket tid som det gjorde. Jag hade ¨aven r¨aknat med att det skulle g˚a att f˚a ut lite data om hur kommunikationen med mobiltelefonen skulle ske fr˚an Sony Ericsson, men eftersom s˚a inte var fallet har arbetet blivit i vissa fall sv˚ararbetat. Om arbetet skulle ha p˚ab¨orjats idag, och jag hade haft den erfarenhet som jag idag besitter, hade jag nog valt att vi skulle ha varit tv˚a examensarbetare om projektet. Detta d˚a det vid ett flertal tillf¨allen uppst˚att problem som hade varit l¨attare att tackla om det funnits n˚agon, som man kunde diskutera f¨or- respektive nackdelar med. Det kan till exempel r¨ora huruvida mikroproces- sorn skall h˚alla uppe kommunikaionen med mobiltelefonen ¨aven om det inte finns n˚agon data att hantera. Kanske vore det b¨attre om kommunikationsl¨an- ken enbart togs upp n¨ar det fanns ett ID att skicka. Om s˚a vore fallet skulle det g˚a att minska energif¨orbrukningen genom att s¨atta mikroprocessorn i sleep-l¨age st¨orre delen av tiden.

3.2. Result

An initiation sequence is sent when a phone is inserted. After that the normal communication begins. It consists of a status question from the hands-free and a status response from the phone.

3.2.1. Protocol

The data line is low when it’s idle. A data frame consists of one start bit (high), one stop bit (low) and 8 data bits at the data rate 38kbaud. It’s assumed that the least significant bit (lsb) is sent first. The initiation sequence is sent with 2400baud. Data line low is considered ‘1’ and high is considered ‘0’.

The SMS provides a means to transfer short messages between a GSM Mobil-Staion (MS) and an Short-Message-Entity (SME) via an Service-Center (SC). The SC serves as an interworking and relaying function of the message transfer between the MS and the SME. The short message point-to-point services comprise two basic services:

⇒ SM MT (Short Message Mobile Terminated Point-to-Point);

⇒ SM MO (Short Message Mobile Originated Point-to-Point).

The text messages to be transferred by means of the SM MT or SM MO contain up to 140 octets (max 160 Characters).

To use the SMS you have to declare the number of the SMSC (Short Message Service Center, SCA) in the MS (Mobile Station), provided that the MS support SMS-MO (Short Message Service-Mobile Orginated).
