We found a problem with a client's legacy design. They use two 12 pF load capacitors for the 32 MHz crystal, which has a 4 pF capacitance. This is a somewhat unusual Abracon...
Hello DevZone,
I have a project where I currently use the AT%XPOFWARN feature, in order to turn off the modem in case the battery voltage is too low. It's used in both cellular...
We use several Nordic chips in our BLE sensors. We bond to the devices from Android, connect to update configurations, then disconnect such that the device then advertises...

In essence, I would like to configure all 4 rows as low driven output...
Hello,
I already searched the forum, but I didn't find anything.
Is there a way to invert a port on a NRF51822?
I use this chip together with an XMega-Chip and they...
Hi,
I'm trying to get PCA10001 board working. I used ble_app_hrs example from SDK 6.1.0 (I'm using eclipse with gcc). The Softdevice is v7.1.0
The application seems...

I would like to start and stop a pwm signal with the buttons on the board(BUTTON_1 and BUTTON_2). The pwm is working fine. But when...
Hello:
I want develop my nrf51822 project base on new sdk and softdevice.In /nRF_Examples/9.0.0/ble_periphera/ble_app_uart/, the keil project device is nrf51422,and it can...
Hi,
I'm compiling the simple blinky example with no softdevice for an NRF51822 xxAA using GCC on linux. I can't get any LEDS to blink off the GPIOs, so I'm debugging with...
I can see a phrase "Not recommended " on the Evaluation Kit's page: www.nordicsemi.com/.../nRF51822-Evaluation-Kit
What could that mean for me if I already have the kit...
I found in ble_app_uart example, any device with UART app can connect to uart service and send something to COM port or just block the connection of other devices.
So can...
I'm trying to update my firmware using the dfu, I tested two examples of the SDK :
one of them is dfu_dual_bank_ble project,
I noticed that the memory allocation...
Hello,
I have been reading a lot of Nordic and DevZone stuff. The information I need appears to (almost) be there but I cannot quite put it all together. I need some help...
Hello, I am asking for your help again.
I just managed to brick the chip that I am working with. The problem is that I am not able to erase or program the flash. However...
