Hi,
I am getting randomly incorrect SOC reported by pmic npm1300. For most days, it reports correct SOC but then all of a sudden it starts to report incorrect SOC even though...
Hi,
I recently found out about the Periodic interval feature on GRTC CC[0] and it seems like it would be quite useful for my application. Most of my code so far uses the...
I found some examples on dev zone how to read RSSI during connected state:
Function report RSSI but as a positive value around 230. How to recalculate it to dB. I see...
Hi,
I have integrated Neuton’s “Transport Type Detection” pre-trained model into my firmware, running on a nRF52840dk. For collecting 9-axis IMU data, I’m using the ST X...
I'm trying to implement a fall detection feature on the headset side using the LSM6DSOX IMU sensor. The IMU is configured successfully, but the board halts after the INT1...
I am using the S312 protocol stack on nrf52810, with both BLE and ANT+enabled, to transmit heart rate. It can be used on most devices, but it is difficult to connect to 'wahoo...
I have a ready hogp struct and I'm trying to subscribe to an input notification (I'm connecting to a bluetooth keyboard) and I'm getting error -22. Here's the callback in...
I am using the LFCLK RC oscillator, 8000ms calibration interval.
Is it possible to read from some register the resulting calibration value for the LFCLK RC oscillator?
Now I work on designing a product, which is implemented by sending LMP commands to a bluetooth device with nrf51822. Unfortunately, nrf51822 liberary could not provide the...
Hello,
measuring ADC signal on P0.26/AIN0/XL2 and P0.27/AIN1/XL1 doesn't work (I get constant value from the ADC not reflecting actual voltage on the pin). AIN2 - AIN7 seem...
I need to send a disconnect command from the app layer. I've seen a few other posts that say to use uint32_t sd_ble_gap_disconnect. One post had this line of code as an answer...
I am using the RBC mesh in a networking product using the nRF51422. We would like to turn the mesh on and off at selected times, say once per hour for a minute or two. I know...
Hey,
I have been trying to set up wdt for my application which services some interrupts once in a while and advertises continuously. I put the nrf to sleep using sd_app_evt_wait...
Hello,
I'm trying to read voltage signals from a sensor using internal ADC and send them OTA. For now, my codes seems to work, but the only problem with my codes is it...
I'm connecting my nrf51 with my phone and when I move far from the microcontroller (long distance) the connection is lost
what's the function witch rise this error and what...
the code of 51822 PAN 73# must be added in SDK 6.0?

hello there i want to interface nrf51 dk with ds3234 using spi. i see spi master example. how to assign SPI I/O pins. can you tell me how to do it?? i find SPIMO_SCK_PIN....
Hello,
I am trying to work with the nrf51sdkv10 and trying to install arm-gnu-gcc toolchain on my MAC-OSx (El-Capitan). I downloaded the 4.9.3 version and installed in the...
For nrf51, the current consumption is more than 1mA when GPIOTE is used since 16MHz clock is always on. Is this fixed for nrf52? or nrf52 still has the same level current...
