* 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。 | ||
具体卡有没有使用高波特率,普通日志看不出,需要取QXDM日志。 | 具体卡有没有使用高波特率,普通日志看不出,需要取QXDM日志。 |
