Summary

The battery level obtained from Stripe M2 connectedReader.getBatteryLevel() is incorrect. Our application actively queries the battery level of the M2 device. The result obtained is 60%, but in reality, it is 100%. This continuous prompting for charging has caused some inconvenience to customers.

The log is as follows.

Hi @OliverYang0305. Are you able to reproduce this with the latest SDK release?

OliverYang0305 commented 9 months ago

@bperez-stripe Hi, I tested on version 3.3.0, and the problem still exists. The return value of connectedReader.getBatteryLevel() seems to always be the battery level at the time of connection.

I got same issue like seems to always be the battery level at the time of connection. I have set timer and every 5 mit checking Battery Level code : Terminal.getInstance().connectedReader?.batteryLevel?.times(100) ?: 0.0F Where else I can found Battery Level or How I can refresh Battery Level ?

Hi all! With the release of Terminal SDK 3.6.0, Terminal.connectedReader's battery level will now be updated whenever the mobile reader's battery info is reported.
