Hi, I am seeing an issue where after enabling read back protection (rbp) on NRF52 and using sdk 12.1 the tag goes to state where it drains a lot of current.
command used: nrfjprog -f NRF52 --rbp ALL

I'm using the PPK (v1.1.0) to measure my nRF52 DK (v1.1.1). My sample programm is very simple: set up the LFXO, RTC with 8s CC-periode and the BSP_LEDs:
const nrf_drv_rtc_t rtc = NRF_DRV_RTC_INSTANCE(0 ...
Basically I want to get a 8 byte long MIC when using the AES CCM encryption. From the product specification it does seem like I can only get a 4 byte MIC, is that correct? Or is there some workaround available?

The spec(nRF52832_PS_v1.3.pdf) said the peak current of TX/RX is 5.3/5.4 mA.
However, I use the PCA10040 board and the ble_app_template(SDK 12.2.0) sample code to measure the peak current, the ... (more)

Hi, I am trying to measure (and reduce) the current consumption of my board. I am using nrf52832 (64K RAM) for my development. The RAM layout is as follows: RAM (rwx) : ORIGIN = 0x20002080, LENGTH = 0x2EA8. Stack is 2048 and heap ... (more)
I would be interested on knowing whether I may have a secondary UART on the nrF52 chip or not. I would like to communicate my nRF52 with a RN2483 and this is done through UART, however I see that ... (more)

I am trying to compile for the nrf52 one of the examples that are included in its SDK12.2, to be precies, I am using experimental_ble_app_blinky_pca10040_s132, I have been able to compile it with KEIL but now I would ... (more)
I'm struggling with current consumption. I need my device to completely sleep and leave only the RTC on when the ext power is off (run on battery). After making sure my RTC was actually working, I ran the following ... (more)
I'm trying to program my nrf52832 with an ST-LINK /V2. I can't get both the softdevice and my app on the chip.

I was reading the procedure to prepare the NRF52 DK board for current measuring and some questions came into my mind. I understand we have to open the P22 so we interrupt the circuit to measure the flowing current ... (more)
