* PSAM卡,slot1(索引index 1)是高通模块支持的,超时时间是1.6s, 所以如果卡response time比较长,大于1.6s, 那么就会disconnect, 所以对有些老卡,速度比较慢的,需要使用slot2(索引index 2)及以上, 超时时间最长是5s。Q3BU比较特殊,有6个SAM卡槽,索引index从0开始。超时时间都是5s。其他机器索引index0都是IC卡。 | |||
* 非接支持A(14443),B(14443),C(Felica),D(15693)卡 | * 非接支持A(14443),B(14443),C(Felica),D(15693)卡 | ||
* PSAM卡baudrate问题:在Q3上波特率是9600到9600*8, 波特率默认是9600,这个速度是卡和模块之间协商的,是一个自动的过程,(if the card can support higher baudrate, when get ATR of the card, the module will send an increase baudrate command to the card, if card support the increase, then the communication will use a high baudrate).Q2P上暂时支持不到38400,模块厂商在查。 | * PSAM卡baudrate问题:在Q3上波特率是9600到9600*8, 波特率默认是9600,这个速度是卡和模块之间协商的,是一个自动的过程,(if the card can support higher baudrate, when get ATR of the card, the module will send an increase baudrate command to the card, if card support the increase, then the communication will use a high baudrate).Q2P上暂时支持不到38400,模块厂商在查。 |
