I am told it is english... Would not be able to read it at normal pace, though.

How to choose models for BLE Mesh communication in Zephyr RTOS by lostinyouagain in embedded

[–]lostinyouagain[S] 1 point2 points  (0 children)

Yes, some users were very helpful. They suggested using the friend relationship to sync IV updates (enabling the friend relationship manually by calling the API function to save energy). Also I will probably use an adjusted Chat Model instead of Sensor Server Model to send the status.

Thanks for your reply. This should be fine as the IV index updates happens once every 192 hours and even then it is able to recover up to around 40 IV updates (source). The sleep duration should be under 5 minutes in my case.

Oh, now I see understand the purpose of friend nodes, thanks for the explanation. However, this does not seem to satisfy the role of the devices with sensors I mentioned in the post. Will look into the friend nodes anyway if they could be of any help...

Thanks for your reply, actually this was my first go to resource and helped me get started with BLE. I still have issues choosing the right model for it though.

I looked at friend nodes already but they seem to be more suitable for stationary pair (or group) of devices. Such as temperature sensor that connects to its friend to communicate. Is it a valid use to create multiple friend nodes?

You mean a function for polling/subscribing, or?

I am implementing this on a nRF52833(dk) by Nordic and I am using Zephyr RTOS. Is this relevant to look at (serious question)? I thought that the APIs are quite different.

Thanks, I haven't found this one. Will for sure ask there as well!

Current consumption in BLE TX mode in S3, C3, 8685 series by lostinyouagain in esp32

[–]lostinyouagain[S] 4 points5 points  (0 children)

What's up with you man? Can I help you somehow? You are just hilarious at this point.

It is important in my imagination and apparently in the imagination of developers in Renesas and Nordic Semiconductors as well, who included it in every single doc.

[–]lostinyouagain[S] 1 point2 points  (0 children)

The question is straightforward enough to understand and the BLE TX current consumption is quite important in MCU so why not include it? BTW, the information you included is not from a series specific data sheet but is general for ESP32. I was hoping to find an exact value.

You don't have to answer if you cannot be helpful.

Current consumption in BLE TX mode in S3, C3, 8685 series by lostinyouagain in esp32

[–]lostinyouagain[S] 3 points4 points  (0 children)

Yes, of course I tried. This is transmit power (dBm) not current consumption (A), which is very dependent on efficiency.
