Control an LED
As explained in https://github.com/dustcloud/smartmeshsdk/tree/develop/app/JsonServer, to blink the LED, you need to issue:
an HTTP PUT request
to URL: http://127.0.0.1:8080/api/v1/oap/{{mote}}/digital_out/INDICATOR_0
with body:
{ "value": 1 }or
{ "value": 0 }
create the following Node-RED flow:
What is the configuration of the "LED on" and "LED off" nodes?
Answer 1:
What is the code you wrote in the function node?
Answer 2:
What is the configuration of the "http request" node:
Answer 3:
verify that you can switch the LED of your mote on/off
Control a Buzzer
Your SmartMesh IP mote has several pins you can control over OAP, exactly as the blue LED.
For example, “digital_out/D4” corresponds to the pin called I_MISO on the DC9003 board.
Connect a buzzer to the board
buzzer pin labeled ‘+' to pin
I_MISOon your motebuzzer pin labeled '-' to pin
GNDon your mote
adapt the Node-RED flow above, replacing
digital_out/INDICATOR_0bydigital_out/D4make sure you can switch the buzzer on/off
