Hi, Right now, We are developing GSM based component for our product which is PPP based component and we have successfully verified it with multiple test-cases. So, I have also looked into LWIP component and found support for PPPoS as well for PPP COMMUNICATION over GSM. So, I am just worried about...

Upload Files to REST Web API

Hi all, I developed an Web API which exposes some GET and POST methods and I'm using ESP32 to access it. One of the methods is a POST that allows to upload files. This method has two parameters: 1. serial: the serial number of the device 2. file: the file I tested the API with Postman and it is work...

Re: ESP32 with MPU6050 via Arduino IDE

FrankenApps, I ran into the same problem with MPU6050 and got a bug in the last version of i2c library in arduino-esp32 SDK. In order to apply a workaround until the next official release, you should download (from github.com/arduino-esp32) and replace these four files: - libraries\Wire\Wire.cpp - ...

Over the Air firmware upgrades with JFrog Bintray

When we develop our IoT apps, we always have to think about the distribution including updates. Espressif allows us to use the OTA solution, that is suitable when we consider that we will deploy a few number of devices, mainly in local network. When we need a more robust solution, there are not many...

Re: ESP32 with GSM modem - PPP over Serial (PPPoS) client example

Hi all, I found some problems in the library. It doesn't support you to disconnect (ppposDisconnect) and reconnect (ppposInit) later because it doesn't uninstall the serial driver. I've made a fix for this. Another change is that I created a parameter ConnectionSettings for ppposInit in order to sup...

Re: ESP32 with GSM modem - PPP over Serial (PPPoS) client example

An update. After much messing around, the solution we've come up with is to leave both interfaces up and to use lwip netif_set_default() to set the default interface based on priority. If you are using standard C sockets, you could alternatively bind() the outgoing socket to a particular IP (again ...
