To be able to upgrade FW through UART, a bootloader for nrf51822 is required in my project. I have tried out the example bootloader in SDK. But this example is using softdevice...
I followed the forum posts and nan-29 to get eclipse 4.3.2 to successfully connect to JLinkGDBServer via a Segger J-Link EDU on Ubuntu Linux.
I can start the GDB server...
I'm using Softedevice 6.0.0 and SDK 5.2. and Keil 4.7.

I am working on the proj that needed 2 MCU and nrf51822 work as slave.
I would like to know any ref on how to firmware upgrade on board without external tool?
We're looking for a Nordic nRF51822 based low profile/small USB dongle that we can use for our iBeacon software.
It would need to come complete with casing and the ability...
Hi all,
i want to establish connection between two threads in cmsis-rtos, can i use
1) semaphore to do this?
2)message queue should be used or any other ipcs can be...
Hi,
I have two CPU in our product. (STM32F2 and Nordic nrf51422).
I use serialization function to link those two CPU(refer to ble_s110_serialization sample)
But I find...
Hi,
After setting up constant carrier, how can one determine that it is working. With no modulation the receiver can't determine anything, can it?
thanks
Hi,
SPI use with SDK14.2.0 leads to very high power consumption (around 400 µA) on nRF52832 (QFAA). The same piece of code running with SDK12.3.0 has much lower power consumption...
We developed a device based on nrf51822.
We use SDK11 and module Device Manager to implement bonding.
We have received feedback from the user, that our deivice was bricked...
Hi,all :
I just want to know how to enable the nrf_log (in the ble example).The version of the sdk is 12.3.0 and the cpu is 51822 .Thank you very much .
On the nRF52810 is it posible to change the gain setting for the SAADC on demand? For example the SAADC is reaching its cap and then the gain is increased so it is posible...
I see the max for a BLE connectable advertising packet of 31 bytes. I am not sure if the manufacturer specific data which also can be up to 31 bytes is included in the overall...
Hi,
We have recently moved from using the nRF52840 PDK to a custom PCB. The custom PCB uses nRF52840 Q1AABB, while the PDK has Q1AAAA.
On the custom PCB, the code is getting...
Good evening,
I'm having some difficulties with the thingy52. I used it as the basis of development for the project and up to this point without major problems. However...
IARv8.x.x no longer seems to display the detailed peripheral register settings in debug mode under "View->Registers" as all v7.x.x versions used to do. In trying to determine...

Hi,
I'm using a nRF52832, SD132, SDK14.2 on a custom board.
I want to use BLE for precision, my use case require me to perform at least 50 reading from the SAADC per second...
Hi,
I'm trying to understand the speed of the BLE communication. What I do in my infinite loop is a SAADC conversion then send the value to BLE (int16_t).
In order to...
Hello,
I have a statically provisioned mesh network (keys and addresses are pre-set in code to make it simple for now) in which each device periodically broadcasts it's...
Hi,
i want to know if there is a solution to apply LE privacy to a timeslot advertisement ?, my problem is :
