Re: Unable to receive TCPIP-packets with wifi callback function

Howdy, You will want to study the API called "sockets". This is a standard C/C++ API that is used to TCP/UDP programming against the TCP/IP protocol. If you can google using the phrase "sockets tutorial", I think you will be rewarded by a whole host of articles. I am also a fan o...

Can you possibly paste the exact commands you used to perform the pull and sub-module fix up?

Re: ESP32 Main Task Size

Howdy ... no sir. Each task you create has its own stack size that YOU explicitly specify when you create a task. If you look at the API you are using to create a task, you will find that the stack size for THAT task that you are are creating is a parameter on the API. Since there are some tasks wit...

August 2017: Caution on using ESP-IDF master with BLE

I had been finding issues with BLE using the ESP-IDF master and raised as an issue here: https://github.com/espressif/esp-idf/issues/857 It appears that the recommendation is currently to use the release version (2.1 seems to work fine) and avoid ESP-IDF master until the related issue is resolved. I...

Using FatFS without wear leveling

When we use FatFS, I find that we normally use: esp_vfs_fat_spiflash_mount This provides an excellent convenience for building a FAT file system that is accessible via Posix APIs on an ESP-IDF partition that leverages wear leveling. Excellent. However I believe it has a draw back ... and that is we ...

Re: I2C with ESP-IDF vs. esp32-arduino

I have found great benefit in getting a $5-$10 Logic Analyzer on eBay. Trying to diagnose I2C or SPI puzzles without one is really hard. With the analyzer attached, you can truly see what is going on at the high speed bus/bit level.

Re: [Video] ESP32 - DS1307 real time clock

I've always needed a logic analyzer (about $5-$10 on ebay) to debug I2C or SPI issues. Looking at the logic train on the wire is (for me) the only way to debug these kinds of issues.

Re: Small ESP32 Modul ( all include in new ESP32-PICO )

I am in awe of you guys building such solutions ... I would love to read a blog article on how you go about the mechanics of this. Specifically, how are you attaching the ICs to the PCB? Are you soldering them yourselves? Is there a "service" that will assemble low volume modules such as t...
