I'm working on an app that is returning -1 on xTaskCreate after I've previously created a few tasks. The heap indicates.... heap_caps_get_free_size(MALLOC_CAP_8BIT) = 1657700 heap_caps_get_free_size(MALLOC_CAP_32BIT) = 1703316 stack free of the calling (creating) task = 7980 When I call uxTaskGetNum...

I ran into an issue where calling "nvs_set_str" occasionally hangs the task and I get either watchdog reboots or reports that the WD isn't being serviced. The task is running at priority 0. I raised the priority to 10 and it appears that this fixed the problem. I then lowered the priority to 1 and i...

Check out this thread... https://esp32.com/viewtopic.php?f=13&t=2330 I recommend that you either use Kolban's C++ library, or refer to IDF_PATH/examples/gatt_server for example code. I had a lot of problems with this using a Samsung S5 phone Android 4.2.2, even though it's supposed to be compatible....

If we look at the parameters to a WiFi scan, we see that it is of type "wifi_scan_config_t". Looking at the current structure definition here ...: That was the first thing I tried. i.e. filling out all the parameters. Made no difference until I looped though each channel 1..13. wifi_scan_config_t s...

I just needed to add this function to my project. And I too found I got no responses. One thing I found that was a problem is the channel parameter. The docs say it's the channel to scan. But the docs don't say anything about scanning all the channels. So I put the scan call in a loop incrementing t...

Just happened to see this. Going to give it a try. Thanks for posting!

Picked up a iPhone 6 today for testing and it works . Apparently there is some issue between the ESP32 and Android 4.4.2 on my Samsung S5 that is preventing it from working. Going to try someone's phone that has a newer Android version next.

Starting to think it might be my Samsung S5 that's part of the problem. I'm able to run gatt_client and gatt_server on two esp32 boards. I'm also able to run my code that is a ble server and when connecting to it with gatt_client modified to search it's name, it connects and queries just fine. When ...

More info.... Starting to wonder if my Samsung Galaxy S5 is part of the problem. I've tried numerous apps like nRF Connect and Bluefruit LE that seem to have a problem. But if I run my code on the ESP32 as a server and then change gatt_client to connect to the name of my board it seems to query the ...
