ESP_NOW_Peer => onReceive貌似不太正常 (IDFGH-13705)

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

在onReceive的回调函数中的数据貌似有点奇怪？和随机？请看截图

Serial.printf("%d ", i);

Should this be Serial.printf("%d ", data[i]); ?
