Is there a way to control the max # of packets be transmitted in one connection interval?
(We want to vary it from 1 - 6, knowing that nordic can support up to 6-7.)
Has anyone had any success setting the configuration register on TMP102/112 temperature sensors via I2C? I'd like to switch the sensor to one-shot mode to further minimise...
Hi everyone !
I'm trying to send data from an nrf51822 to an nrf24l01 with arduino and I guess I'm doing something wrong...
