Hi, I wanted to ask a question regarding sending data.
I currently have external memory that will send out serial data (SPI) to the nordic microcontroller. I have saved...
Hi, I just started working on nRF52 with Bluetooth, and I have some concerns about DFU and security.
I’m working on a product equipped with an nRF52 and a MEMS microphone...
Hi!
I am using the NUS service and I noticed that Android 6 (Marshmallow) will not go faster that 47.5 ms. Even iOS can go to 30ms. My target is 7.5.
Am I doing something...

I'm migrating an app from SDK8 to SDK11 and I'm getting errors using TWI to communicate with my IMU (Invensense 9250). I first tried it on a nRF52 DK (Eng B) and then went...
I've either got a bug in my code or the JLINK connection is dying. Either way it's a real headache to pinpoint and discover how to resolve. Knowing more about extracting info...
Hi, Now I use the NRF51822 ADC to sample VCC , 1.2V internal reference,internal prescaling 1/3.The PCB connection show as the pictrue .My application develop base on soft...
Hi,
I would like to make some measurements via I2C in radio_notification_evt_handler. Unfortunately, after executing a random number of measurements, the advertising stops...
I'm trying to make a BLE device that actually pairs securely. I posted this question on StackOverflow but didn't get any answers - maybe someone here knows more. As far as...
Hi,
I am wondering which frequency tolerance is acceptable for the HFXO, as in the product specification, p.105, a maximum value of +/- 40 ppm for Bluetooth low energy...
I am using a PCA10036 board, and the UART app library in SDK 0.9.2. I have sequestered all of my UART functions into one module. To keep things organized, I would prefer not...
