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,
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...
Hi,
I am trying to bond the nrf51-DK with the android smartphone. I want to display the passkey to the user which would be done using BLE_GAP_IO_DISPLAY_ONLY. After which...
Hi, would there be any drawback in setting TIMER_PPI_CH_START to 11 to maximize the number of free PPI for application. 14->15 should be free to use in timeslot and ppis are...
hi, i am new to embedded system.
I am using SPI interface to collect data from the slave(imu) and transmitted it to nrf52 DK,previously,I just used RTT to show the received...
Hello,
I am truing to store data in the UICR register "customer area" from application code. The procedure is invoked only once when the registers are still empty. The...
Hello all,
In controlling two devices simultaneously from one central controller, I have noticed significant time delays in processing the second call to sd_ble_gattc_write...
Hi.
I am using PCA10028 board an SDK10.0.0.
nRF51's Max flash size is 256KB.
Q1. "s130_nrf51_1.0.0_softdevice.hex" size is 302KB already. How can we make HEX file less...
Hi.
I'm using PCA10028 and SDK10.0.0, S130 v1.0.0.
And "ble_app_hrs_c" example is my reference code.
It works well before i add code for timer as below.

Is there a difference where I initialize uart in main? My code is able to run when I shifted the uart_init() after ble_stack_init...
Hi,
I am trying to figure out which GPIO pins i can use as UART on a nrf52 chip if i put it on a custom PCB (Not DK !!). From the reference manual (page 513, 48.10.7 and...
hi,
i want to restart my timer before it expires.
suppose my timeout is 2 second and i want to restart it in between 0-2 second based on signal when i receive before expires...
I've notice that the ST Balun NRF01D3 that I've used for my current design is not listed as compatible with Rev 3 (Build code: H) nRF51822 Silicon. Has there been any change...
