6.3.2.3 Asynchronous Response Format

The ADC module generates asynchronous responses after each conversion. This value returned is an instantaneous value upon receiving the AT command. The response format is as follows:
+ADCRDVAL: <Value>, <Channel>
  • Value: This field represents the instantaneous digital value obtained from the analog-to-digital conversion. It can range from ‘0’ to the maximum value supported by the ADC resolution.
  • Channel: This field indicates the channel number from which the conversion was performed. It can be one of the supported channels.
