EXTERNAL BAlTERY CHECK

by Michael Weyrich

ABSTRACT

  This paper decribes a method to prevent portable radios from being damaged by software upgrades caused by low battery.

INTRODUCTION

  Normally there will be no check if the battery has enough power to drive a complete software upgrade procedure or programming of a portable radio.

PROBLEM(S) TO BE SOLVED

  If a portable radio is programmed by a field pro- grammer or upgraded by a software upgrade utility it can happen, that the battery's capacity is too low to drive the complete procedure. If the power fails during this procedure, the software or user specific

data could be lost and reprogramming at the manu- facturer's service is the only way to get the radio back to work. To prevent a damage of the battery, some radios will be switched off driven by software before the battery's power is too low.

PROPOSED SOLUTION TO THE PROBLEM(S)

  Before a field programmer or software upgrade utility begins its programming, it should check the battery level by sending a command over the pro- gramming interface. If the battery level is too low, either a warning can be displayed to the customer and the programming software will ask him, if he really wants to try the programming with the risk of loosing data or the software can display a message that the battery has to be charged or changed before the programming of the radio is allowed. This idea can also be used for other programmable devices than portable radios which are powered b...
