Ciao! Dopo aver eseguito i primi test con il protocollo MQTT e Arduino (in questo post), passiamo ora ad semplice esempio pratico. In questo caso piloteremo 2 led collegati alla Wemos, direttamente dal prompt dei comandi del nostro pc, tutto questo grazie al Mqtt e Mosquitto. Per prima cosa è necessario collegare 2 led alla Wemos in questo modo: Dopo aver effettuato i collegamenti carichiamo nella Wemos il codice che trovate qui sotto, inserendo SSID e password della vostra rete wifi. E' necessario inserire anche l'indirizzo IP del broker, se il broker Mosquitto sta girando sul vostro pc Windows, potete scoprire l'indirizzo IP digitando "ipconfig" nel prompt dei comandi. /* Derivato dall'esempio "Basic ESP8266 MQTT example" della libreria "PubSubClient" www.danielealberti.it */ #include #include WiFiClient espClient; PubSubClient client(espClient); //sostituisci ssid e password della tua rete wifi const char* ssid = "********"; const char* password = "********"; //sostituisci l'ip con quello del broker (indirizzo del tuo pc se usi mosquitto) const char* mqtt_server = "192.168.***.***"; //nome di questo client, sarà visibile dal broker const char* clientName = "ESP8266_n1"; const int pinLed1 = D0; const int pinLed2 = D1; long lastMsg = 0; String msgIn; int value = 0; void setup() { pinMode(pinLed1, OUTPUT); pinMode(pinLed2, OUTPUT); Serial.begin(115200); setup_wifi(); client.setServer(mqtt_server, 1883); client.setCallback(callback); } void setup_wifi() { delay(10); Serial.println(); Serial.print("Connecting to "); Serial.println(ssid); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); } Serial.println(""); Serial.println("WiFi connected"); Serial.println("IP address: "); Serial.println(WiFi.localIP()); } void callback(char* topic, byte* payload, unsigned int length) { msgIn = ""; Serial.print("Message arrived ["); Serial.print(topic); Serial.print("] "); for (int i = 0; i

I wrote an article which demonstrates how to build an inexpensive Bluetooth bridge between an SiK telemetry radio and an iOS device. The article will be of interest if you’re building telemetry or ground control station software for iOS. When I first started working with Pixhawk I was frustrated that I couldn’t use my iPhone as a development platform. I’m glad to have finally solved that problem. The problem is that iOS doesn’t provide the required operating system level libraries to communicate with serial port interfaces such as those on SiK radios. You could attempt to join Apple’s MFi program but that's out of the question unless you're a company intending to develop an accessory. Solving radio telemetry for iOS involves hardware, and at the core of the solution is an ingenious bit of kit from RedBearLab named BLE Mini. Other common Bluetooth modules are simple serial port adapters over Bluetooth, however these are useless for iOS. In contrast, BLE mini provides a Bluetooth…
