There is the board mark on the chip like n51822CEAAD01350A0, where DO is Build code, 1350 is tracking code(YYMM), A0 is lot code.
My question is how can I get those codes...
I'm trying to debug a randomly occuring Hardfault. In trying to trace down the source I read the CPU registers use the Nordic hardfault_implementation.c which grabs the register...

Hi,
I am a bit confused about power consumption when using app_uart_fifo. To save power I put MCU to sleep in between each sent and received byte by using __WFE and __SEV...
Is this even possible? I have a BLE connection with an interval of 7.5 ms. I've set up a radio notification with a distance of 2680us in order to be able to transmit 4 BLE...
Hi,
I want to know how sd_ble_gap_authenticate api works.After executing this api, what are the events invoked at peripheral end. Is there any event that blocks CPU or...
We are designing product based on nrf2401A
The problem that we encountered was that the nrf2401A forgeted configuration data, was it possible ?
we use our product in highly...
Hi,
I am using the nrf51822 in an intermittent high-current application where if the battery is close to dead, will sometimes cause the chip to reset because the voltage...
I am using SDK 8.1.0 and Eclipse on a Mac. I am having difficulty flashing my app that uses the nRF51 sdk onto nRF51. I am using JLink
I assume I need to flash two things...
Hi nrf51 developers,
I'm developing multiprotocol application by combining BLE and a proprietary protocol. I'm using concurrent multiprotocol timeslots API. Started with...
I am new to programming both the nRF518122 as well as the Cortex-m0. As I have been building and running the example apps that come with the nrf51 sdk, I run across the CMSIS...
Hello,
I'm developing device application where I need:

I have enabled data ready interrupt bit and also enabled the fifo bit and also enabled gyro_fifo and accel_fifo bits in mpu6050 so that when data ready interrupt occurs the...
I have a nRF51DK. The Softdevice on the board is S110.
I load the ble_app_template from the SDK 8.1 on the chip. It builds with success. Now with the MCP I am able to see...
I'm now using the lastest SDK 8.1.
I found that if I call app_button_enable() after app_button_disable(), app_button_enable() would not function again.
But if I changed...
Hi all,
I read that the nRF51822 comes as a blank chip from the factory, and this means that we have to program the SoftDevice ourself. I am wondering if this is the only...
