[Hilo] How long pulse of POK_IN needed to start up?

[Hilo] How long the pulse of POK_IN is needed to start up? When module can answer AT commands after module start up?

Answer: To start the module, a low level pulse must be applied on POK_IN during 2000 ms.
After a few seconds, the CTS will go to active state once the module is ready to receive AT commands.
Also if you receive URC of “+KSUP: 0”, it means module is ready to handle AT commands.
