STM32WLE5(RAK3172) - Why do we need to initialize and de-initialize the ADC function again and again for every read, whether this method is effective?

[Praveen_PK]

I'm currently working on stm32WLE5(RAK3172) for that module, and I'm using SDK 1.0.0V 

 1) In that LoRaWAN stack for battery reading implementation, we are noticing that the ADC initialization & de-initialization happening every time.

My question is, why do we need to De-initialize every time? Instead, the initialization can happen only one time before the while loop. So that we don't need to de-initialize & initialize every time.

We are observing that the battery value is constant if we implement it like the previous scenario.

Kindly support this. 

Thanks in advance!
