Low cost SIM modules

HI All, I have a project which uses the SIM800L module to use the mobile network to send SMS and make a call. Since the SIM800L only supports 2g and 2g is being phased out I want to replace it with something else. I communicate from the ESP32 to the SIM800L via AT commands so the replacement would i...

SMTP example code issue

Hi All, I am using the SMTP sample code within my project and the surrounding code uses the code to send a status update email every 2 minutes. Most of the time it all works fine but every now and again I get the following error in the log when it is trying to send the "FROM" field. E (8307017) smtp...

esp _log.h causes random TG1WDT_SYS_RESET / RTCWDT_RTC_RESET in C++

Hi All, I have been having random resets (TG1WDT_SYS_RESET followed by RTCWDT_RTC_RESET) and core dumps. From the logging, I could see the odd corrupt characters but could not work out what is corrupting it. I have now been able to reproduce it with a minimal test and the results are a bit odd. The ...

Re: V4.2 Linux install.sh bug

Thanks very much for your reply. I ended up deleting my idf directory and doing a fresh clone and still no joy. I then rebooted and tried install.sh again and it worked fine. I suspect something must have been running which prevented the virtual environment being created? Seems very odd to be honest...

printf causes SMTP Email Client issue?

Hi All, Quick update. I have narrowed down a line that is causing the problem (at the moment at least) although not sure this is the root cause to be honest. I have the following line before I call the method (I wrapped the smpt sample code in a class) to send the email (which ultimately calls the w...

SMTP Email Client issue

Hi All, I have a project which initialises wifi on the main thread then creates an email task which looks for messages on a queue and sends via email. The email task is the smtp_client_example code. Sometimes this works fine but when I change unrelated code it seems to fail with "mbedtls_ssl_read fa...

Re: Python issues and suggested updates

Thanks for getting back to me. For me, install tools in eclipse did not work on its own. I seem to recall the issue was when I clean generated IDF app, it came up with python dependencies issues but rather than the ones I had seen before where it says the dependency it only had python. I concluded t...
