Re: ESP32 NimBLE Controller

I can only answer part of your question... can I use the NimBLE controller with the ESP32? Yes, I'm using it presently and find it easier to work with then the Bluedroid stack. I do not believe it has made it into a release yet, so you will likely have to use the master branch. The documentation to ...

Re: Hard-reset not working

Interesting.... and maybe a bit concerning? I'm using the CP2102N-A01 and have no issue flashing from several different Linux machines. Do you have any further reading on this issue?

Re: Hard-reset not working

I'm using this part successfully in several of my designs. First thing I notice in your description is your reset circuit, typically this is implemented with two transistors and two resistors. Here's one of my recent schematics https://cdn.hackaday.io/files/1638617010629024/coffin.pdf . Additionally...

Re: NimBLE port for ESP32

Yup, did see that and mostly what I used as my basis. Working on adding a couple more services and will report on any issues I have.

Re: NimBLE port for ESP32

Super cool! nice work all around. I spend some time yesterday evening digging into this branch and the results are good! First off, it's quite a bit easier to use than Bluedroid, I reduced my overall code by about half. I was able to follow the heart rate example easily and within about 30 minutes h...

Looks awesome! I'm just gearing up for a new project and will give this a spin for the BLE needs.

Re: MESH Broadcast Message

Curious if anyone made progress on this. I'm trying to get group sending to work but having no luck.

In addition to the code above, I'm adding the MESH_DATA_GROUP flag as per the API guide. But yeah, still nothing.

Re: Make issue

I recall hitting something like this before, try running git submodule update from the esp-idf directory.

Guidelines for external antenna layout

I'm designing a board with an edge mounted SMA connector for the antenna and am looking for design guidelines. The hardware design guidelines briefly outlines using a PCB antenna but not much more. Is there a reference design available for an external antenna? I see mention the ESP-WROVER has an ext...

Plans for complete BLE stack (ATT, GATT, etc)

Is there any followup to the announcement that CEVA will be providing the BLE stack for the ESP32?
