I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
We've heard that the BLE transmission packet length may be increased beyond the limit of 20 bytes in a future version of the S110 softdevice. Would you let us know...
Hi
I struggle to understand mechanisms of switching particular subsystem of nrf51822 off and on again in order to consume as little as possible current when MCU is put...
Hi
I have an ADC that just recive, but i will need to make an buffer that makes tx values and just send them to a output pin.
So I wonder how i should code this and if...
