Re: writing to NVS

That's my understanding. The NVS subsystem un-burdens you from the low-level gorp and all you have to think about is what you want to store and retrieve and how to name it ... and NVS takes care of the mechanics of actually doing the work of storing and retrieving it for you behind the scenes.

Re: writing to NVS

Could you be missing the point of NVS? The idea behind NVS in ESP-IDF is to hide from you the complexities of reading and writing flash storage. The model of NVS is that you can create name/value pairs and NVS takes care of saving them for you and retrieving them when you request. When working with ...

Re: writing to NVS

For about 1K of data in total, written/re-written once a day and everything else being equal, I'd suggest using NVS and call it good.

Re: Simple TCP communication over wifi

As Mr fly135 wonderfully illustrates, there is nothing "special" in ESP32 TCP/IP programming. Now, of course, as soon as I said that ... the idea of "special" is subjective ... so let me explain. For many decades there has been a programming API available in C for working with TC...

Re: writing to NVS

To me, the key information on whether to use NVS vs File System is based on: 1. What is the total amount of data you may anticipate having stored at any one time? 2. What is the "write/update" rate? How often are you creating new or updated data? Once, once per hour, once per minute, 20 ti...

Re: Unable to connect to EPS32

Next thing to try is attaching a serial monitor (eg. putty) to the boards at 115200 baud. Boot the board with the reset/EN button and see what (if any) messages are logged in the case of the "good" board and the "bad" board. Make sure you use the same USB cable in both cases.

Re: What is the right JTAG Debugger for the ESP32

As a data point ... I use Eclipse (on Linux) for JTAG debugging.

Re: Simple TCP communication over wifi

Is your ESP32 going to be a TCP/IP server accepting incoming client connection requests or will it be a client attempting to connect to an external TCP/IP server?

Re: presoldered ESP32 module

The raw ESP32 is a 5mm x 5mm IC that can be surface mounted. By and large it is not usable for hobbyists like me. The next level up is the WROOM and/or WROVER modules. These are ESP32s with flash encased in a small PCB inside a small module. They have no "pins" but can be just about solder...

Re: Advice for IDE for an existing project

Howdy,
It isn't clear from your post whether you want to stick with the Arduino IDE and work in ESP-IDF or whether you want to use a different IDE (eg. Eclipse) and continue to work in Arduino APIs.
