Богдан Лошинский Posted June 26, 2015 Share Posted June 26, 2015 Hello. I'm using HC250 controller and trying to receive data from the device through the serial port. The indicators on device are blinking (RX and TX), but function ReceivedFromSerial in the driver don't calling. Asked me, please, why is it happened?

msgreenf Posted June 26, 2015 Share Posted June 26, 2015 Did you make the connections between the driver and controller in composer pro?Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

In another case the RX and TX indicators on the device were not to blink after my commands. The device worked on PC and I received right answer from it.

RyanE Posted June 26, 2015 Share Posted June 26, 2015 A few things to check: * Does the device require hardware flow control? If so, you won't be able to use the 3.5mm pin adapter, since it only provides GND/TX/RX. * Is the baud rate set properly? RyanE Link to comment Share on other sites More sharing options...
