I was trying to send BPM integer values using my pulse sensor through the nordic bluetooth low energy chip to the NRFUART app. The problem is that it does not send the bpm when requested. Please take a look at the attached photo.

Hi,

Can you post the actual code for sending this, its difficult to see in just a screenshot.  A few questions - what is BPM and what values can it have?  You are also hardcoding to send just a single byte at time, this should be the size of all the data that being sent in any given transaction.

Thanks,

Ken
