what is micro-ESB ? nRF52810 have AD（Analog to Digital）?

[tony55723]

Hi，

I finally want to integrate BLE and 2.4G in nRF52810.

【1】I am studying  Timeslot，i found some articles in DevZone.

There is a mention of micro-ESB ， so what is micro-ESB ? （There are many abbreviations that don’t understand what it means）

【2】I need to detect the voltage of the lithium battery, no instructions for this section were found in the nRF52810 documentation.

Keyword is AD ? or other?

（Forgive me for studying mobile apps before ， MCU knowledge is not very sufficient）

Thanks all

well typing 'micro esb' into google gives  https://github.com/bjj/nrf51-micro-esb as the top link. I can't find a much better explanation than the readme on that repository.

Please note that recent SDK versions include ESB libraries which are based on uESB. For new implementations I would suggest to use the ESB protocol implementation that comes with the latest SDK versions.

However, if you need to communicate with legacy ShockBurst devices, you might need the uESB implementation instead.

Do you mean a rechargeable lithium-ion battery  (3.7 Volt). As the nRF5x is supposed to run on lower voltages, you'll need a voltage divider. Then you'll need to look for the SAADC examples for the measurement itself.

Thank you for answer，

The phone is connected to Device A (BLE) and sends data to Device B (2.4G).

I don't want the phone and Device A to be disconnected. I should know the timeslot.

There are mentioned timeslots in this article.

But I don't know ， I want to achieve function,  need to use micro-ESB ?

I work hard to learn knowledge，if i have a mistake, please bear with me , sorry

============

Yes, the lithium battery is 3.7V

Regarding the detection of lithium batteries, I did not consider the 52810 only 3.3V.

I will study SAADC examples, thank you.
