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...
I use a app_timer_create() function to create a task(200ms once)
when in the task_timeout_handle() ,
I do something more than 200ms,
what will this timer going ?
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;

I've been using nRF24LE1 for development. The HAL library provide the AES encryption for ECB mode. Now I need the decryption function. Does anyone has the realization? Any...
Hello everyone,
I use SDK14.2 and s132 softdevice. I can read "NRF_SAADC_INPUT_AIN0" and "NRF_SAADC_INPUT_VDD" pins and system is working properly.
Working Code like...
Dear friends,
I am using the nRF 52832, s132. I want to know the BER (bit error rate) of the BLE link. How can i measure it? Further, to what extent do other radio interferences...
Hi.
I want to know the time difference between functions by using a timer instead of a difference. I've looked at app_timer.h, but it's hard to understand.
I do not need...
I am trying to use the ADC to take power measurements on an interval. I found an example to read the values out online:
void ADC_IRQHandler() { nrf_adc_conversion_event_clean...
I am designing a PCB using the NRF52832 and this antenna . The antenna design guidelines suggest ground clearance and direct traces from the NRF52832 to the antenna without...
I am working on a project which I wish to Paer between to nRF51422 devices and to use the auto reconnect between them. there won't be any display so it must be automatically...
Hi,
is it necessary to use internal regulator for NFC DC/DC or we can use normal internal LDO in design.
also if we need to use internal DC/DC regulator, what is the...
Hi, I have tried to find a solution for some time now in the Nordic Semiconductor forms.
We have been noticing a peak or a disturbance in voltage in every connection interval...
I have encountered a scenario in which my application is terminating the BLE connection via a call to sd_ble_gap_disconnect, while around the same time I receive a write request...
I'm able to successfully use peripheral/uart example to read the data from GPS module. I achieved the same by setting baud rate to 4800, and connecting rx and tx of GPS to...
Hi,
Question about FOTA (firmaware upgrade over the air).
I know that nrf52832 has 512 kB of flash, and the ble stack( softdevice ) has 136 kB , and the bootloader has...
Hi,
I put my NRF52 to sleep (POWER OFF mode) and configure it to wake on GPIO port event like so:
This GPIO is set up on a reed switch. Occasionally, the NRF52 will...
