I'm programming my ESP32 with the ArduinoIDE and have a problem with HTTP GET. What I'm doing:

- the ESP32 connects as WiFi client to an existing WiFi network using a static, fixed IP

- a webserver is started which provides a webpage for OTA firmware update -> this works, the webpage is accessible ...

I make use of following code to scan for Bluetooth-devices:


BLEDevice::init("");
pBLEScan = BLEDevice::getScan(); //create new scan
if (pBLEScan)
{
pBLEScan->setAdvertisedDeviceCallbacks(new MyAdvertisedDeviceCallbacks());
pBLEScan->setActiveScan(true); //set passive scan; active scan uses ...

Works - thank you very much

Hi,

as one can see in many examples (like e.g. the one from https://sourceforge.net/p/iot-leaf/code/ci/master/tree/BleDHT22/BleDHT22.ino ), the advertised name of a BLE-server typically is set up once during initialisation via a call BLEDevice::init().

Now for my application I want to change it ...

The whole code is way too big. What is shown above is the complete Wifi initialisation. Beside of that there is a webserver bound to this IP:

#include <WebServer.h>

server.on("/",eventIndex);
server.on("/woff.html",eventWoff);
server.on("/graph.svg",drawGraph);
server.on("/graphL.svg ...

I'm programming an ESP32 via ArduinoIDE and stumble upon a strange problem. It operates as WiFi access point, the code is quite simple and straight-forward:

IPAddress apIP(192,168,1,1);

WiFi.mode(WIFI_AP);
WiFi.softAP("MyESP32");
WiFi.softAPConfig(apIP,apIP,IPAddress(255,255,255,0));

Now when a ...

I would prefer to combine this handgenerator with a battery too

If somebody is interested: these guys here at https://iot.halaser.de offer a ESP32-board which supports power via USB or solar cell, which includes battery charger and deep-discharge protection and is prepared for LoRaWAN and GPS. Seems to be everything that is needed for portable/autonomous ...

Great - Thanks!
