HL76xx UART with no hardware flow control

Hi,

Does any one know how to configure HL76xx series for UART - No hardware flow control to send AT commands?

-AJ

Based on mangOH Green schematics HL and WP can work with UART1 Rx and Tx lines only.

Let me know if you have other thoughts.

Thanks
AJ

Hi ajegan,

From unexplainable, the modules are delivered with the factory setting at+ksleep=1.
This prevents normal communication. :imp:
So you must first set at+ksleep=2 to work normally.

Hi WISTE,

Thank you very much for your wonderful information.
