Hi!
My idea of sending a packet would be:
-regulary send a packet with fixed length (stated in static length field) to a base: i.e send the temperature =>4byte
-if...
Hi,
I use the nRF51822 on the PCA10001 and nRF6310/PCA10005 boards. I modified the radio_tx_example and wanted to read the actual state of the radio. Therefore I used a...
