Hi,
On my single I2C Bus, I have interfaced 4 I2C slave devices.. Now my voltage level of this bus behaves randomly. sometimes It shows 3.3V, but most of the times It stays...
Hi all,
We are currently under FCC certification testing for our custom BLE module based on nRF51822 but failed with the average power exceeding the limit. Nordic Semiconductor...

I found that when compile the code with...
Hello,
I am getting data from UART and extract NRF BLE packet.
I check the CRC Flag and its OK. But sometimes the UART has some error and I have to check the 3 CRC bytes...
Hi all
I have issues with E-INK display for signals I need 100ns and 500ns delays
but in nrf delay is only nrf_delay_us()
What is easiest way to get nano delays with...
Hi,
I've been working on a way to detect and prevent replay attacks when beacons are used for sensor data. This is mostly used for home automation sensors, where I have BLE...
Hello,
Can you share with us the balun of the nRF52 chipset or at least the ZLoad equivalent, that is R + jX value.
The Balun if the nRF52 is a 6-Element Balun or 4...
