This is great stuff! I'm trying to connect to a server at 192.168.1.20. It is a Ubiquiti ethernet radio. In your example, you create a connection to the (http://loboris.eu/ESP32/test.php) domain. The output you get if verbose is enabled is * timeout on name lookup is not supported * Trying 82.196.4....

Kolban, I asked about the issue on the libcurl email forum, and I was told I could use a new flag "CURLOPT_SSL_CTX_FUNCTION". I found this example online on how to use it. It is only available in the latest release of the library (7.54.0). I've updated the libcurl library and I'm on 7.54.1-DEV. I al...

Kolban, Thanks for your help! Everything was very clear. I was able to disable the watch dog timer, for now, to debug my problem. Once I did, the program just sat there indefinitely. I added the verbose flag to give me more to work with and the following was the output. * timeout on name lookup is n...

Kolban, Thanks for showing us how to get curl working. I'm working on a project that requires me to use https. I'm connecting to a server with a self signed cert. I use curl_easy_setopt(hnd, CURLOPT_SSL_VERIFYPEER, 0L); curl_easy_setopt(hnd, CURLOPT_SSL_VERIFYHOST, 0L); to get passed any warnings. T...

Thank you. I updated the IDF, and make menuconfig gave me the options to disable the gatt client. It cut down the code enough for OTA to work.

THANKS!

I think my problem is the size of the code when I'm using bluetooth. When I just compile the bluetooth code with everything else commented out (basically the example code from the idf), the size is 872224. When I compile my project without the bluetooth code the size is 591472. Compiling my project ...

I've recently starting using the BLE on my application. OTA updates were working just fine before I starting using BLE. Now, if I try to run an OTA update with the BLE code running, I get the following errors: I (15703) ota: Connected to server I (15703) ota: Connected to http server I (15703) ota: ...

I've upgraded to the new IDF (2.0), and my BLE code is having a few issues. When the board is reset, I get the following: BTDM CONTROLLER VERSION: 010101 btip start copy .data from 4000d890 to 3ffae6e0, len 00001830 set .bss 0x0 from 3ffb8000 to 3ffbff70, len 00007f70 BTDM ROM VERSION 0101 BD_ADDR: ...

I am using two MCP23017 port expanders on the ESP32. Everything was working great until I upgraded my idf to v2.0. My code no longer controls my MCP23017's, and it doesn't throw any errors. The pins on the MCP23017 don't change, and I get random values back from the read. Below I have code for my re...

Got it working! Thanks Kolban for your help. My problem was with localtime(). Before using it, you have to call time(). time_t now_after; time ( &now_after ); char buff_after[100]; strftime (buff_after, 100, "%Y-%m-%dT%H:%M:%S.000", localtime (&now_after)); I do have one problem. Sometimes the reads...
