I read this older post ( devzone.nordicsemi.com/.../) and have a similar issue but with enough differences that I felt it was worth a new question.
I have an STM32 MCU...
I am having an issue with running the initial blinky example that came with the nRF51 PCA10028 SDK in the Eclipse IDE . I will include screenshots of the issue. I believe...
I use nRF51-DK and nRF51-Dongle for a BLE sniffer.
Always the sniffer fails and marked with an error "Encrypted packet decrypted incorrectly (bad MIC)".
It can not be...
Hi,
I'm using long write in one characteristic but if I try to configure this characteritic with write authorization (attr_md.wr_auth = 1) it doesn't work. I need to send...
Hi, I disassembled an Acer Mouse and saw a chip named "NRF A 3152c 1517UH". Can anyone identify the chip or provide me with the data sheet for it.

After i asked this question , i changed to use SDK 8.0.0 hrs "s110_for_dfu",
As the same step to try,
i downloaded softdevice(s110) & bootloader(for 8.0.0)
then opened...
Hi!
Can you please recommend a LDO IC for a USB/Li-polymer Battery power for the nRf51822 please? The LDO needs to drive the nRf51822 and a couple of sensors such as Gyro...
I'm trying to get the ble_app_hrs example working in Eclipse, but the stack pointer is not setup correctly. It's at the start of the RAM (0x20000000), and therefore it already...
I'm implementing an Android 4.3 app which uses an nRF51822 and the BLE proximity profile. I have the following as starting points for the app code:
The BLE sample...
I can't seem to find the required current of NVMC doing erase and write. The product spec has only timings but not more. Could someone from Nordic provide some figures? Experimental...
Hi,
I have a C# app connecting to 51822 devices, doing data/firmware download. When I try to send erase page command (before write), erase works, but there is a disconnect;...
Should we keep track of this by monitoring the write events or poll the gatts value via the softdevice?
It looks like it's faster (+shorter = less consumption) to monitor...
Over the past few months I have worked extensively on a few different projects that all utilize the nRF51422. In some recent debugging of GPIO issues (both relating to SENSE...
As the title says, I am wondering when the new SDK will be released to support the nRF51822 hardware revision. It looks like the latest (v4.4.1) doesn't have anything new...

Hi, i'm experimenting RTC1 using the app_timer module (not using S110 soft device), and i find some problems onRTC prescaler. If i set values as stated in the datasheet, for...
Hi,
I am trying to run several applications sequentially on the nRF51822.
I have another microcontroller controlling the nRF51822 by SPI.
I init the stack, the services...
Hi, I'm just wondering if there's a reason that the example code is always initializing all structures through functions. Has it something to do with sleep mode and RAM retention...
Hello,
I have a couple of questions about sending multiple notifications:
I want to send multiple notifications (from same characteristic), is that allowed by...
