My sensor is off-standard,so I have to use gpio to read and write my sensor.
Gpio IIC will take about 0.5ms to get data.
My app need send data every 7.5ms,it seems that...
Hi,
My android Proximity application fails on service discovery only for the very first time it connects with the devices(nrf51822 evaluation kit with sdk 5.2.0). Actually...
Has anyone converted the app note AN34 DTM Python script to C# or C/C++ ?
The Python DTM script is works OK with the setup specified in the app note AN34 figure 2, which...
Hi,
I have a serious problem, when I use uart of NRF51822 QFAAC0 to receive data from another MCU, I found that it will lost one bit at same position everytime. my SDK is...
Hi,
I just started to interface the lcd display with nrf51822 evaluation board. The display i'm using is, spi compatible, 18" tft (160x130) from tiny lcd. I took spi master...
Hi,
We are using the nRF905 device in an application where it needs to switch between auto-retransmitting and sending single packets, due to it communicating with several...
I have two characteristics inside a same service - one characteristics notifies periodically and another on demand. I call sd_ble_gatts_hvx to send notifications with appropriate...
Hi all,
I got strange behavior: when I disable the SoftDevice (nRF52832, S132 V3.0, SDK 12.2) seem that ALL the RTCs, not just the one used by the SD, are stopped, and...
Hi.
I got the ble_app_beacon example to enter System On low-power mode (and operate in the 1 to 2 microamp range except when broadcasting). And I also got that example...
Rather than using previous timeslot examples for esb and ble multiprotcol, can we manaully switch between both protocol, what kind of process need to switch from ble to esb...
Hello,
I am building a project that required pwm drivers and BLE UART. I started by using peripheral ble uart example in SDK 12 and adding the pwm driver source file from...

I'm using sdk14.2 peripheral examples fds and fstorage in an attempt to test flash storage persistance (with softdevice present).
The two examples are quite intuitive...
Is there any way to invert the PWM behaviour easily? I'm trying to develop firmware that will run on the DK52 (LED active high) and my custom board (LED active low).
I...
Like it says in the title. I'm working on an embedded application where lifetime is pretty important, so I'm trying to get power consumption down as low as possible. I don...
I have Rx sensitivity issues when DCDC is enabled
The 52832 datasheet shows these connection:
DCC: 10 uH,
DEC4: 15 nH
When switching both inductors I get better sensitivity...
Hi, I am have been using PPI to control SPI transfer in response to a GPIO interrupt.
The PPI initiated SPI transfer that reads an external device's register A and I would...
while the ble_uart example is a great resource of information, i have a need to completely separate the ble nus data in / out from the hw uart code
using sdk 14.2.0
