Hi All, I have ordered an ESP32 development board which has a GSM module. I have been looking for a good recently updated GSM library so I can send/ receive SMS as well as dabble with voice calling. I have seen TinyGSM seems to be popular on the Arduino forums but it doesn't support receiving SMS. I...

Hi all

I have found some articles online talking about using a pi as a JTAG debugger. It looks like this can be used to real time debug an ESP32. Has anyone actually got it working? Anyone know of a good tutorial?

Thanks

Lee.

Hi All I have seen that QEMU now supports ESP32 as a virtual OS and looks like you can run and debug ESP32 apps on Linux without deploying to a physical device. I have also seen QEMU eclipse plug in which implies you can even debug from Eclipse. I tried to get QEMU up and running but am struggling w...

Hi All, I am using the coap library that is bundled with ESP_IDF. I have to upgrade it to the latest version but am struggling to do so. I have tried replacing the existing coap directory with the new one but get compile errors where it can't find the include files (e.g. coap.h). As far as I can see...

Thanks very much for your reply. I have now stumbled upon coap which seems to be bundled with the IDF so am giving that a try. Anyone else tried this?

Any ideas anyone?

Thanks for getting back to me. Sorry I am not sure I follow your last response. In my example, I am receiving a message via espnow. If I understand correctly, the receive callback will be on the WiFi task (thread?) . I then call the mesh send from the callback - (ie on the same WiFi task). Shouldn't...

Hi all, I have been looking at the coap library which is bundled with the IDF and managed to get the client server example working fine - it uses an asynchronous get. I modified the code to enable the client to "observe" changes and the initial get seems to work fine. The trouble is, when the resour...

Hi all, I have seen the coap examples and found some documents on the protocol. I can't seem to find any documentation on the sdk/ lib itself and how to use it. Anyone found anything? There is also a simple bug in the example (I've raised on git) so wonder whether this is very new and hence why I ha...

Hi All, I have built a ESP32 mesh and now looking at options for passing data between it and an Android app and Alexa - e.g. reading values from sensors, sending data to sensors, responding to "push" notifications from nodes etc. I have seen the sample apps here https://github.com/EspressifApp?tab=r...
