首先感谢作者提供这个demo,一股清泉,网上资料太乱了,能提供一个热敏打印的demo格式就更好了。
打印机正常,用风火码小程序可以正常打印
用demo写数据,通信灯闪,但是不打印
console显示:发送完成 errCode:0 errMsg:writeBLECharacteristicValue:ok
这是报错吗?
二维码打印可以成功吗?请问一下
下载您的demo后,成功的连接了打印机,但是在getBLEDeviceCharacteristics获取特征值的时候,
read
write
notify
indicate
全部返回的是false
经过测试打印机本身是没有问题的
中文标点符号有问题,汉字和英文标点符号没问题
文字里面有中文标点符号会乱码
