Hello,
I built my application based on your "ble_peripheral_lbs_coex" example. Board is nRF5340DK.
Mesh and BLE (NUS service) run together but I noticed that the NUS UUID...
I'm using SDK 17.1.0, softdevice 7.2.0 as a Bluetooth peripheral. I'm sending notifications to a paired iPhone. The notifications are keyboard keys, and so are time sensitive...
Hello,
I am trying to figure out how to save a small number of counters to local non-volatile memory on the nRF9160. I have a few questions.
1) How do I determine whether...
Hi
I want to measure chip temperature of nrf52840.
For this I referred " sdk-zephyr / samples / bluetooth / peripheral_ht / src /hts.c"
