Trouble and solve ways:
Troubles 1: Between devices not communicated
Cause and Remedy:
1. Communication at both ends of the air rate, parity inconsistency
2. Frequency inconsistency
3. Without power
4. Module has destroyed
5. The pin of sleep mode not set
Troubles 2: Module cant communicate with PC
Cause and Remedy:
1. Without power
2. TTL to RS232 converter is damaged, or without power supply
3. Converters .module.pc with connection error
4. Change work channels
5. Serial port baud rate settings are not correct or air, to re-set
6. Power supply ripple big, replace the power supply
