Re: ESP32 + LP55231 IC2 gremlins

What I2C clock frequency are you using?

Looking at the data sheet, it seems that the max is 400KHz ... but that is the max. Can we try at a lower clock frequency?

Re: How to get the rssi from BLE scan

The formal docs can be found here: http://esp-idf.readthedocs.io/en/latest/ A free book is available here: https://leanpub.com/kolban-ESP32 There are some good resources on YouTube ... see: https://www.youtube.com/playlist?list=PLB-czhEQLJbWMOl7Ew4QW1LpoUUE7QMOo and https://www.youtube.com/playlist?...

[Video] ESP32 - Building a C++ Application

I've been on a kick recently working in C++ with ESP32 and am very much enjoying the pairing of the two. I've been using C++ in some of my previous videos and been seeing a number of questions on how to get a build environment going with C++. This video provides a walk through of the steps that I ch...

Re: connected wifi stations

Well hmmm .... that was harder than it should have been. From my study, I believed that the answer was the tcpip_adapter component but after a search I could'nt find any docs in the web site on that component. Has it been accidently missed from the inclusion in the web based docs? The answer to your...

Re: A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header

My opinion is "yes". I use Windows 10 as my desktop OS but use VirtualBox running Ubuntu for all development for ESP32. In addition, I am of the opinion that platformio isn't ready yet for GOOD ESP-IDF platform development and am trying to see if that community is willing to work with the ...

Re: How to get the rssi from BLE scan

I'd like to second what neilyoung said ... Ive started to study platformio and think I see that it currently has limited integration with the ESP-IDF technologies. It might work fine if you are staying exclusively in an "arduino" platform but if you are working in an ESP-IDF platform, it i...

Re: Third party IDF components list

I'd like to offer up a suggestion. I'm a big fan of "pulling resources" in a common community mechanism and unless there are dramatic distinctions from one option to another, I recommend and follow the majority. Which takes us to the subject at hand ... repositories of ready to use librari...

Re: ESP32 - Arduino - Connecting to a local server

I think Martin had it spotted earlier. Domain names that are "xxx.local" are "special". Let us assume that you are trying to resolve the domain name a.b.com. Your ESP32 will connect to the DNS server you have defined and will ask it "Please get me the IP address for a.b.com&...

Re: I2C: protection against connection (lines) problems

You bring up an interesting concept/question. I'm wondering (out loud) if the concept of "pulling" an I2C device is has any kind of valid semantics. I am going to stick my neck out and say that I2C is not like USB or a UART which were designed from the outset to be able to be connected/dis...
