Hi As part of attempting to write code for self testing I'm trying to measure the HFXO frequency using the LFRC (we don have an LFXO) I'm expecting that the measured HFXO...
Hi,
We're planning to design a custom board using the nRF9151 for LTE connectivity. We'd like to add basic BLE support, with the following constraints:
The BLE chip...

Hello,
Is it possible to use easyDMA to transfer from GPIO to memory without involving the CPU? We need to read from a parallel bus for a short duration, without losing...
When setting up a 1Mhz square wave using NRF_PWM on the NRF52 or GPIOTE on the NRF51 while BLE is advertising, the PWM stops when the radio is active. The problem doesn't...
Hi,
I'm developing a BLE application for the nRF52 and I wish to use directed advertising and the whitelist.
I initialise the Bluetooth advertising using the following...

Hi,
I believe there's a minor bug in low_power_pwm.c regarding pwm_state.
The routine low_power_pwm_start sets the pwm_state to NRF_DRV_STATE_POWERED_ON ; but it then...
I've a PCA10036 V1, I change the IC to nRF52822 QFAA-B016. With nRF5_SDK_11.0.0-2.alpha_bc3f6a0 and SD: s132_nrf52_2.0.0-7.alpha_softdevice, the programme started but if I...
I am troubling shooting some issues between my device and iPhone using nRF Sniffer.
One of the errors the sniffer captures is this:
