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 designing what is essentially a small beacon board built around an nRF51822. On the antenna outputs I've used the discrete component balanced to unbalanced circuit shows...
Hi,
Will PAN item #56 TWI: TWI module lock-up be fixed in the Rev 3 version of the nRF51822/51422?
Also would you happen to have a time frame as to when the Rev 3 will...
nrf24LE1 external interrupt is not easy to use , I use nRF24LE1 48pin chip, and the external interrupt 0 (GPINT0)is configured to falling edge trigger, but it can not be triggered...

Everything was fine until I updated to the latest SDK version 6.0.0 and the new nRFGo ap version 1.16.1. Now when I try and connect to my device I get J-LinkV4.52c Error ...
Hi all,
I am trying to send and receive generic data from the L2CAP layer. So, initially I am just trying to send data with sd_ble_l2cap_tx with S110. The code that I am...
We are considering moving from the nrf51822 wlcsp to the qfn48.
We would like to minimize the changes to our design. Can we, should we keep our wlcsp antenna design and...
Exactly what baluns are known to work with the nRF51822. I believe there is the STMicro balun and am uncertain about the status of the Johansen balun. Is there a list of preferred...
Hi,
We are using nRF51422 in our project and we observe a strange thing, that even there is no external pull up resistors, the I2C communication using the built-in TWI...
Hi,
I am trying to power off and/or disable a RR[0] with no success.
I am Powering OFF the watchdog in main and then successfully POWERing ON in wdt_init but then I...
Hi,
I am trying to create a star network with 12-16 slaves and one master.
The master would be a nrf51822 and the slaves nRF8001/2.
The slaves would not transmit...
