Hi,
I used nRF52840 dongle device to run BLE multi-link Central and nrf52832 to run BLE Blinky example to test the communication of 20 nodes. How can I set and verify that...
I am making a BLE device that uses 7 ADC inputs. Most of the inputs need to read at 1hz or so. Two of these inputs are of interest
The first is a heart-rate signal that...
Hi,
I want to measure ADC for 3.3V
Using formula
RESULT = [V(P) – V(N) ] * GAIN/REFERENCE * 2 (RESOLUTION - m)
Rearranging eqn:
Vin = ( RESULT*REFERENCE)/(2 (RESOLUTION...
Hi,
Does every nrf9160 chip have its unique chip ID? if yes, is it the one which can be read by the AT command AT+CGSN ? and can it be used as the board serial number? ...
