Hi
I generate a pwm signal via changing the state of one characteristic. In general, the pwm works fine. But the problem occurs when I add the timer which is responsible...
Hi guys,
I use the 51822's PWM recently, PWM is made by GPIOTE+PPI+TIMER, and the PWM source code as below(I use TIMER1, GPIOTE[0], PPI_CH[0], PPI_CH[1], period and duty...
Hi all, I'm asking on both BLE specification version 4.0 (or more) and NRF51822 S130 about having support for multiple central connections at the same time while our NRF51822...
Hi,
I get RSSI values like -96 or -97 dBm before the coded PHY connection between two nRF52840 pdks drops. Are these values something expected? TI advertises sensitivity...
Hi, there~ Nordic's Mesh SDK is fascinating! I was thinking of a way how to connect the Internet with Nordic's Mesh devices.
