Hi,

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

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

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.
