Re: ESP BLE Mesh v0.6 Released, SIG Certified

Dear All I'm planning to use BLE mesh to send/receive custom customs buffers (max 64 bytes each) to/from a mobile app (provisionner) to multiple devices (ESP32) provisioned from the mobile app. I'm new to mesh and cannot find any suitable model to send/receive customs buffers.

Thanks for this release.

What is the esp-idf version included in the ESP BLE Mesh v0.6 branch ?

Re: Weird RAM alignment

Problem was coming from char OriginationDate[10]; that was not aligned to 4 bytes.
Replacing this char OriginationDate[10]; with char OriginationDate[12]; also resulted in 668, which makes sense once you know the alignment is 4 bytes.

Re: [SOLVED] Boot Different Partition from Application

Re: What is the purpose of two OTA partition?

You cant do it, because you cant overwrite active (currently running partition) The running partition would not be the application to update, but the partition where the boot loader is stored. From my point of view, this should work : - Download a new fw from Internet to the SDCard from the main ap...
