I have been facing a few issues with the BLE custom service, I am looking to create a Pedo meter service which displays step count information received from the sensor...
Hi Guys,
We have designed a custom board which is using BMD350.
Our application requires using the BMD350 in beacon mode and then going to sleep in low power.
We have...
