When I turn on Hm-10 Bluetooth module, it's LED blinks for 5 seconds and then it become still ( the led is always on without blinking ).

At these 5 seconds I can find it when I make a search for nearby Bluetooth devices and I can enter to AT command ( I write AT and it returns OK), after the 5 seconds can't find it with search and when I use AT commands it does not respond.

Can you help me to figure out the problem?

我在使用 Hm-10 时也遇到过同样的问题，当我带上另一个时，它工作得很好。问题可能是硬件问题，你必须更换它或固件有问题（我上传了另一个固件，问题没有解决，但可能另一个固件会解决问题）
