We would like to be able to calibrate the rRF9E5 ADC
Our proposal is to permanently fit voltage dividers, each using two precision resistors, on two of the ADC Ports and...
At some point in the past I had nrf51+gdb+breakpoints working just fine. I even have a bunch of __BKPT() calls in my various error handlers to trap into the debugger.
At...
Hi,
I'm trying to program nRF51822 Beacon Kit using nRF51DK. I'm trying to load the example ble_app_beacon to the beacon kit. After uploading SoftDevice 7.1.0, I try to...
Hello
I'm using the nRF51 DK and I have a UART over BLE link set up between the board and a phone with the nRF UART app. I'm trying to get the board to execute a particular...
Hello there guys i been reading your 100 pg PDF for awhile now and im yet to understand or realize how is it that i add/place/create a payload or data to send/Tx via Master...
I am interested in writing a BLE central that reads data from multiple BLE Nordic sensors. The BLE central will be running on Embedded Linux which uses the BlueZ stack.

Hi,
I'm trying to get S110 softdevice (v8.0.0) working with RIOT. I had some issues (I couldn't initialize TIMER1 or TIMER2 until softdevice is setup & enabled) but I think...
Hello!
Thank you for the excellent SDKs and documentation on the NRF52. I am developing several user devices on the NRF52 DK PCA10040 and my own boards using the Garmin...
Hi,
I am trying to receive packets from a device with Zigbee custom profile. Through sniffer, I can see that the device joins the network and sends packets on it but I cannot...
Our board doesn't have LFXO, but I want to run DTM. When I try to switch to LFRC by changing sdk_config.h, it doesn't take effect.
chip: nRF52832
SDK: nRF5_SDK_17.0.2...
Hi, we use the Fanstel BT40 design a RS232 & USB carrier board, when we use battery 3.3V to VDD, there is a DC2.8V output from VDDH. VDDH should be power input, why there...
As known in SDK nrf there is a function battery_level_in_percent() used to calculate battery percentage but it is only true for the CR2032 battery. Currently, I am using AAA...
My application uses a SPI LED driver, which I routed on a PCB to the most convenient pins for routing.
I have already tested my firmware on a nRF52833 DK with an Arduino...
Hello, I'm a beginner at developping nrF52832. My problem is completely similar to this one : devzone.nordicsemi.com/.../add-saadc-peripheral-and-others-to-example-project...
I am trying to measure single-phase mains voltage (240v, 50Hz) by stepping down the voltage to 200mv using a voltage divider and read it with the ADC pin of the controller...
Using NB- IOT JIO SIM in india, not connecting asset tracker Work Up to RRC Connected and stuck there. This is custom code very similar to asset tracker example. We are using...
Dear Sir.
