Hello.
I would like to develop FW for the nRF52832, using Eclipse IDE + ARM GCC + Segger JLink OB.
I've seen on the segger webpage that the nRF52832 is a Cortex M4 processor...
When using app_timer through scheduler, a break and go will overflow the event queue if a timer is a repeat timer. The effect is that it's not possible to debug.
To work...
I need to be able to actively set the value being incremented in the Timer2 register on the nrf52 (what I believe would be it's main register). It seems that this might be...
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 there,
I was trying to understand "sleep" power modes of the chip (CPU + Peripherals) in a bit more details - but my understanding is that everything is handled by the...
Hello guys,
these days i started to work with the CryptoCell library on nrf52840 and i'm facing some issues running AES CCM* mode

Hi there,
A little background in my experiences first: I've programmed a couple PIC24 microcontrollers in the past for VERY simple embedded system projects (i.e. making...
hi:
I am working with the nrf52832, and the radio transmitting data packet.I find the receive data is ok, but the crc indicate a data error. Why? This problem is same with...

We are working on the system based on BLE_APP_UART_C (central) and BLE_APP_UART (peripheral).
“Central” is always “ON” and scanning for the peripherals...
HI there,
I read somewhere here that the SPIM3 bus would be capable of 32MHz operations in the "next" chip revision (that was 6 months ago).
Could you confirm that it...
I have created a device that will connect and pair with one central. I would like it to re-connect automatically after disconnecting because it was out of range or turned...
I can connect/pair/bond to the nrfConnect app and disconnect then reconnect just fine. When I try to do the same to a central running on arm bluez 5.43, the second and subsequent...
