Story

Here is a supplementary contribution to the Bluetooth HM-10 with Arduino and different shields.

Using a PHPoC Blue and an LED, it shows how to light the two internal LEDs (30/31) and an external LED on port 13.

Since PHP is using another IDE (PHPoC debugger instead of Arduino IDE), I have formulated this information in a separate article.

That may seem strange, if a PHPoC device, which has WiFi, should control via Bluetooth components. But the reasons are in the backup area as a second way, if the WiFi intentionally or unintentionally fails and in the case of lower energy requirements. In my case, it's more about "knowing how".

Wiring

PIN Overview here.

From BLE HM-10 <> PHPoC Board:

GND <> GND
VCC <> 3.3V
RXD <> U0TX/4
TXD <> U0RX/5

and generic LED with long leg (+) into 13 and short leg (-) into GND.

1 / 2

Flash Code

via PHPoC Debugger (Update v1.5.0 is out!) to the PHPoC Board.

If you need a kickstart into PHPoC check this article.

Install Smartphone App

Search for a Serial-App in your Smartphone Store like the free version "Serial" or "ELEGOOBLE" and connect the App with the BLE Modul via Bluetooth.

Test

In the app's chat, submit a 1 to enable the LEDs and a 2 to turn off. The digits or other entries are transported and evaluated via the serial port.

Interesting that the two internal LEDs on the command LOW are bright, right?

This will be explained in the forum and is related to the circuit of the PCB.

Thx to Homer for support! Check his other PHPoC-Examples!

Control your PHPoC Blue/Black with BLE HM-10

<?php

// Mapping BLE HM-10 to P4S-34x
// GND <> GND
// VCC <> 3.3V
// RXD <> U0TX/4
// TXD <> U0RX/5

include_once "/lib/sd_340.php";
$rbuf = ""; // Var for reading data

uart_setup(0, 9600); // Configuring UART0 to 9600bps

echo "PHPoC Example : P4S-34X / UIO / bright LED on Port 13 and 2 internal LED via BLE Modul HM-10\r\n";

uio_setup(0, 13, "out low");
uio_setup(0, 30, "out low"); // internal LED30 on - why?
uio_setup(0, 31, "out low"); // internal LED31 on - why?

while(1)
{
uart_read(0, $rbuf); // Reading data from UART0 into $rbuf

if ($rbuf == "1") {
uio_out(0, 13, HIGH);
uio_out(0, 30, LOW); // yes, low to put internal LED30 bright
uio_out(0, 31, LOW); // yes, low to put internal LED31 bright
echo "LEDs bright\r\n";
} else if ($rbuf == "2") {
uio_out(0, 13, LOW);
uio_out(0, 30, HIGH);
uio_out(0, 31, HIGH);
echo "LEDs off\r\n";
} else {
echo "Command <$rbuf> not known\r\n";
}
}
