Hi.
The reason behind this post is that I want to measure the battery level similar to this post:
http://e2e.ti.com/support/low_power_rf/f/538/t/234130.aspx
There you state that it might be available in the (upcomming) 1.3 release, which was in december 2012. Now half a year later, I sit with the same problem.
Now I tried adding the battery service, yet I can't get it to link due to these errors:
- Error[e46]: Undefined external "HalAdcSetReference::?relay" referred in battservice
- Error[e46]: Undefined external "HalAdcRead::?relay" referred in battservice
I discovered that there is no hal_adc.c in
\Components\hal\target\CC2541ST
of the ble1.3.x stack. (neither in 1.3, 1.3.1 or 1.3.2). Only adding the header in the \hal\include folder, doesn't solve the problem.
Is there any way I can measure the battery level on the SensorTag ? I need it for a business application where it is set in a hermetically (airtight) container, so its critical to know its battery level without taking the battery out.
Thanks in advance :)
