Hi,
I noticed in the nRF54L QFN48 reference design, for the NRESET pin, there is an RC filter (1Kohm series R and 3.9pF shunt cap). What's this for and is it necessary?...
Hello,
I am using a nrf5340 dev kit. When I use SPIM the output from the pins gives the correct hex values but the output's amplitude is only around 100-200 mV. I know that...
Hi,
I'm using the nRF52840 with the SoftDevice for BLE. In my system, it's primarily a BLE transceiver controlled via SPI by an external TI MSP430. We're considering implementing...
Hello,
I want to request AGNSS information from nrf cloud services using my nRF9151DK board. As a first step, I flashed the nRF Cloud multi-service application onto my DK...
Hi,
I'm using cdc_acm to create two COM ports on a PC -
// USB support
& zephyr_udc0 {
cdc_acm_uart0: cdc_acm_uart0 {
compatible = "zephyr,cdc-acm-uart" ;

I am looking for a minimalistic schema design using BLE for collecting data from i2c (twi) sensor and sending them over blue-tooth to the receiver. I need the following features...
Hello,
I would like to know if there are any restrictions in the amount of external memory (RAM, Flash) that can be added to a system using a nRF51822. In that case which...
Although there are some posts dealing with bond manager issues, I have not been able to find a similar issue. I am using part of the BLE code from nRFready Desktop 2 v1.0...
Hi,
i have some trouble with acting with the nrf 51822 ADCs. My Problem is that i have an Impuls which is 100 uS long and i have to measure it with 2 ADCs. I know that...
Hi,
What will happen when we press the service discovery button in the master control panel? do we get any event like BLE_GAP_EVT_CONNECTED? I couldn't find any detail regarding...
I'm looking for information to start developing BLE slaves with nRF51822, but I can't find any datasheets/SDK. Do I need to buy the Development Kit in order to have that?...
I have an issue with my keyboard working with the windows suface (on windows 8.1). Occasionally, the last character sent is repeated several times instead of one. I do not...
On the nRF51822, I see that by programming the readback protect register, one can prevent reading code regions 0 and 1 from the SWD interface. However, if one had access to...
Hi,
I just watched a webinar from the bluetooth SIG on how to create source code from the nRFgo Studio for the nRF8001. Is the same possible for the nRF51822? To create...
Hi,
We modified the ble_app_hrs code to work with accelerometer peripheral, and we have created some custom characteristics with custom uuid's. Now we need to set the device...
Hello, Everyone:)
Nice to meet you !
Please could you commennt my first question on this community zone.
I've a question for the accuracy of synthesized clodk 32k on...
Hi
i am using NRf51822 custom board. In that i have NOR(spi0) and LED(i2c0).
But switching from spi0 to i2c0 is not possible so that i am not able to switch
off led...
Hello,
I'm using nRF51822 to implement a proprietary radio protocol. My first attempt, in the receiver, was polling the EVENTS_* registers. An example:
NRF_RADIO-...
I was trying to get access to the app_uart library, so I included app_uart.c in the "Source" folder; then added \Include\app_common and \Include\ble\softdevice in order to...
