https://devzone.nordicsemi.com/f/nordic-q-a/68018/52832-nus-0（中文） 我在串口透传 NUS 的例程基础上开发，做了以下修改： 1. 最大传输包长 NRF_SDH_BLE_GATT_MAX_MTU_SIZE 设置成了 247 如上图所示，当蓝牙从机发送数据包时，蓝牙主机接收到的部分字节总会变成 0. 而且变成 0 的字节位置总是固定的。 请问应该如何消除这个问题。 （English） My development based on BLE NUS examples.

I will make this case private if it helps. I think the problem must be in the application layer, possibly on the master side. Because packets that are correctly passed to the Softdevice&#39;s send function are more or less guaranteed to be sent and received correctly.</p> <p>Best regards,</p> <p>Vidar</p> <p></p><div style="clear:both;"></div>
