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...
i made this project to try to create RSC service on arduino

unfortunately the server starts but i'm not able to...
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 planning to implement a mesh network, where each node (ble device) also acts as a scanner, detecting BLE advertise messages. The mesh network would then forward the advertisement...
I noted on the release notes for S110 v8 (DRGN-5556, NRFFOETT-986), that enabling/disabling blue_radio_notifications() while the Stack is not idle can cause an assert. Does...
I need something in excess of 5mA output drive. Is there likely to be any problem with connecting two or more GPIO pins in parallel(providing I use OUTSET and OUTCLR to ensure...
Hi,
I have created a project with Keil 5.15
The simply blink app works. Now I want to play with softdevice.
The only problem is... no matter what I do, my hex file always...
Hi ALl
I have permanent error on connect command {0x05, 0x0F, 0x3f, 0xff, 0x40, 0x00 }
When I use security option, with or without PassKey. Return message is 01-03-84...
hey,
so today I updated my NRF Tools... I guess i was using an old version before.
To test our prototypes we have a test fixture where the board is programmed at the...
I'm looking to maximize the throughput using Gazelle on the nRF51.
Assuming zero retransmissions, I believe the theoretical max should be (1/TimeslotPeriod)*PayloadSize...
There is some doubt about the nRF2401L+ RF matching circuit.From the article of <<Tuning_the_nFR24xx_matching_network.pdf>> ,it says "The balun-function is done by the 180...
Is it possible for a nrf51822 running s130 to advertise and scan at the same time?
I am trying to scan for other BLE devices using s130 softdevice, but cannot find an example...
Hi,
I have learned that you can change the MAC address on a device by using sd_ble_gap_address_set. However, when I press the sw2 button on the beacon (running a modified...
While reading about setting up nRF51 development environment on OS X , I came across the following:
Unfortunately the only way to erase
the memory is to do some magic...
Hello everyone,
I am trying to communicate among 2 NRF24L01+ modules using 2 ATmega16A microcontrollers.
My SPI communication is working fine as I am able to write and...
