nRf51 HTS function on nRF Connect but not on nRF Toolbox

[jean-marc]

I develop a temperature sensor sending a temperature and battery status every second. Used to work fine on previous nRF Toolbox. Today on my Android 6 and latest nRF Toolbox only the battery shows the value. The nRF51 bind OK (battery value also works) but no values shows on the temperature.

nRF Connect sees the notifications coming up and shows the temperatures and battery values. Also my embedded development works fine with the nRF51.

What could be the problem with nRF Toolbox?

Found the solution: I was sending NOTIFY and the nRF Toolbox seems to need INDICATE. Modify my firmware sending INDICATE an worked out but cannot find indication on what tells me that it has to be INDICATE and not NOTIFY. Any one could help me to understand more about the subject. Thank you if someone can answer. jean-marc

I just know that the according to the HTS specification the temperature measurement shall use indicate, not notify. See this.
