HttpClient.get() fails with -1
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 v...

BLEScan crashes whole ESP32 on second call
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 more powe...

BLE: Change advertised name during runtime?
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 from...

Re: ESP32 as WiFi access point crashes on connection
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",drawGraphL); s...

ESP32 as WiFi access point crashes on connection
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 clie...

ESP32 Board with solar, battery, LoRaWAN and GPS
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 applica...
