Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...

Hello,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...
I'm currently looking a bit into the bearer-layer internals of the nRF SDK for Mesh and noticed that there is a heap of instances where data needs to be transferred between...
Hi,
I am using nRF52840 and BLE coexistence (mesh and ble). I am able to connect to my board via BLE using nRFConnect for PC and a nRF52840-DK and change characteristics...

The SDK v16 package has a board file for the nRF52833 board, PCA10100, however this seems to reference GPIO pins which are not present on the device:
What should these values...
We use the nrf52832 in twi-master mode. The connected slave sometimes needs longer to respond than the default configured TWI timeout.
The timeout is defined inside the...
Is it possible to generate a zip package containing both firmware and softdevice in such way that the soft device will be updated only if the current device softdevice version...
I have some module chip connected to the nRF9160 DK providing the sensor data over I2C line. In some state transition of the module the short reset pulse needs to be generated...
Hello, I am using BLE secure bootloader example on nRF52840 with SDK 15.3 and softdevice 61.1. I can see the bootloader protects the MBR page and Bootloader space using ACL...
When I run "AT+COPS=?" WITHOUT a SIM the modem always responds properly.
When I run "AT+COPS=?" WITH a SIM the modem does not respond as expected. I get error after approx...
Hello everybody.
I have been working on nRF52840 for a time. I am trying to flash the chip with ble_app_uart_c (SDK 15.3.0). I have applied everything essential, but my...
Good morning everyone,
I am facing an apparently common problem (reported with some variations Here , Here or here ) which is driving me crazy. In the linked discussions...
I am using function "modem_info_json_object_encode" to encode modem info into JSON to send upstream.
I get the very strange format where you encode dictionary as string...
I am curious to know do we have any practical BLE based products such as Fitbit or heart rate monitor, in which there are different type of messages are sent from one end...
nrf_crypto_svc.c throws a bunch of errors during compilation. The errors have to do with SVC_REGISTER_FUNCTION. Example error message: function 'SVC_REGISTER_FUNCTION' is...
