The errata for the nRF52 indicates higher consumption in managing timers and GPIOTE. Does the BSP for SDK11 follow recommended practice to deal with these errata can I ask...
Hi,
I am trying to understand the pstorage to record a log for temperature. In my code, I can call pstorage_init(), and clear a block but when I try to store some data...
I would like to source a compact BLE board to act as a lock controller developed with with a matching transceiver for use in a fob and an app.
It would toggle the pio and...
Ok so here is the issue. I was trying to build a simple application which is described in the tutorial for characters. After building an advertisement and understanding the...
I was working with IAR and SDK10.0 before. For some reason I have to transfer my project to Keil and SDK9.0. My program worked well for the old settings. While keeps got NRF_ERROR_SOC_NVIC_INTERRUPT_NOT_AVAILABLE...
Currently we are considering whether we should use external Flash Memory or NRF52 Internal Flash.
External Flash memory has a lot of drawback in comparsion with internal...
Suppose there are 10 BLE peripherals in a room and one BLE Central,then is there any way i can get the list of available peripherals[name or id.. etc]?
I am using NRF5182...
Hi,
I need to design a board that connects various sensor to a smartphone using the Bluetooth 4.0.
I'm interested in the NRF51822 chip but i have some doubt about what is...
Hi, I'm very new to programming microcontroller, so please go easy on me. :(
Firstly, apology if my post sounded weird, this is because English is not my first language...
Hi all.
I am making a custom PCB with nRF51822 SoC. For my project I need to achieve long Proximity range around 350 Feet. Where my Board will communicate with iPhone....
I have a timer that sends BLE data to a central every 5 seconds. The timers starts immediately out of reset. Until I actually pair the devices, the nRF51822 outputs an error...
I have problem to debug when I use softdevice it frezzes. At the moment I debug the program part with out use of softdevice is there any other solution? It the same code with...
Hi all.
I am new in nRF BLE. I am planning to buy an nRF51822 Kit but little bit confused with choosing EK or DK. Actually my plan is after playing with the Native Kits...
I am currently designing a board using the nRF51822 chip and I would like to implement a soft power ON circuit using the low power comparator (LPCOMP).
I understand that...
Hello,
I'm using a code posted on this forum to read ADC input and fill an array with the ADC values but I always get values between 166 and 174, (even if I connect the ADC...
I'm completely out of ideas.
I've been developing a server for some time now based loosely on the ble_app_hrs sample using the 5.2.1 SD. Things have been going reasonably...
After I process some data (command) received by UART fifo module (I have installed handler for APP_UART_DATA_READY) I need to do a short atomic operation of a few instructions...
We have a project where we would like to use a balanced / dipole pcb antenna. As far as the great docs on the site stands, it's all for unbalanced / monopole antennas. Any...
Hi,
In my application I need to control a nrf51822 central device by an external MCU.
Does Nordic provide solutions to control a nrf51822 Cental device (with S120 softdevice...
Is there a register, accessible via the SWD-DP and present across ARM devices, that I can use to distinguish the nRF51822 from other microcontrollers?
Thanks,
-c
I can discover RFduino BLE devices that use the 51822 using the Master Control Panel but cannot with the nRFTemp app. The nRFTemp app scans for but does not find my RFduino...
Hi,
I have nRFStartet Kit, nRF51822DK and EK.
What is nRF2739? I am just following the setup section in nRF51SDK and it says to connect Master Emulator to PC. Is it...
