I'm looking at interfacing a typical Wheatstone bridge sensor to the nRF51822 ADC. This particular sensor only requires a mA or two for excitation and the output fits within...
When use the "nRFBeacons" app to update the info on my beacon the following happens:
Go to update tab.
Select "Connect"
Press "SW2" on beacon and see the LED begin flashing...
I am using s110 and nrf51822. I've set up up a long characteristic of 154 bytes.
Sending between 1 and 154 bytes works as expected.
Sending 155 - 160 bytes gets rejected...
Hi,
I tested the nrf beacon application, it allows only the beacons with company identifier 0x0059 (nordic's id). But i need to modify it to support all the device, how...

Hi!
I use nrf51-pwm-library ( github.com/.../) to control brightness of LED RGB light source and it works ok till I don't want to adjust brightness slowly (dimming function...
hello,
are there any completed sample code of using pwm0, 1?
just 2 or 3 word can working like following? or need other config?
pwmcon=xx;
pwmdc0=xx;
pwmdc1=xx;
also...
Hello!
When collecting dc1.4v with SAADC, there is an error of 100uv. SAADC is configured in differential mode, with N-terminal connected to GND and p-terminal connected...
Hi,
I've read in these forums and seen the machine instructions within the C code that nrf_delay_us (which BTW is used to do nrf_delay_ms) is implemented by executing a...
Hi team,
I would like to know the default channel used for data transmission and the frequency of the channel.
Also whether the frequency is configured in the softdevice...
What is the purpose of the external capacitors on DECA and DECN? DECA calls for 1uF and DECN calls for 0.1uF. The datasheet calls these out as "Regulator Supply Decoupling...
Hello,
sorry to border you again, but I have a problem that block me for many days. I read all nordic questions on TWI (I2C) but did not found a solution... :(
I have...
Hi,
We are designing a custom Board using nRF52840 SOC.
We are operating it in Normal mode, using an internal DCDC converter
We have used configuration 5 from the...
Hi there,
I need to transmit 33995520 bytes from nrf52 peripheral device to a Windows/Android device. Currently it takes about 13 to 14 minutes to complete the data transfer...
the flash of the nrf52832-QFAB is 256KB. the softdevice S132 is used which consumes 152KB and the compiled file of the BLE_UART only consumes 98KB (after making the changes...
Hi,
We have a product already on the market for about 2 years, based on nrf52840 and nrf52832.
The product receives data from an 'external device' via UARTE, forwards...
I received the product update notification via email. I did not see any additional details such as a PCN which documents the exact changes.
So the questions I have are:...
Hi Devzone,
I have noticed that some examples, like "ble_app_hts" that has strange flash placement like this figure:
There are 3 partitions, each is 8 bytes in top of...
Hi
I was using the MESH SDK 5.0.0 Dimming Server Example on nRF52840 DK and Dongle it worked fine so i designed a custom Board according the Designrules of Nordic. ...
Hi
I want to measure the battery power by using SAADC to measure the value of VDD，The battery to be considered is 4.2V or 3.7V lithium battery，How should the circuit be...
