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...
Hello,
I just received my Thingy:91X which I purchased through DigiKey. I am trying to connect it to hello.nrfcloud but I keep getting the following message: " The fingerprint...
With reference to the Thingy:91x reference design, I see that the LNA (SKY65943-11) on the GPS signal path is powered by one of the switching converters from the nPM1300:...
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 trying to provide a custom peripheral service with a 128-bit UUID in an nRF51822. I would like to use two bytes of the UUID to encode a piece of information unique to...
Hello,
am I right to assume that if sd_ble_gattc_write returns anything other than SUCCESS, then the packet was not queued?
Is this also true for BLE_GATTC_EVT_WRITE_RSP...
Hey guys,
I have a little problem on a new board comunicating with a MPU9250 sensor.
Chip version is nrf52832-QFAA-BA
GPIO PINS Used P0.20 (SDA) and P0.21 (SCL)...
The S332 v0.6 has been released and it is supposed to be compatible with SDK11. My concern is that in the release notes of SDK 11, it says "Temporarily removed support for...
I tried the above example but it hangs here:
while (ser_sd_transport_is_busy());
Not sure why, I'm using GDB to step thru code, and it appears always busy...
Is there...
Device: NRF51-DK
I'm using GDB+OpenOCD to step thru code and it appears that the nrf51 resets itself after calling:
SVCALL(SD_BLE_GAP_ADV_START, uint32_t, sd_ble_gap_adv_start...
I want to make rs485 communication with nRF51822. I gone through the UART code, there CTS , RTS pin are required , but for my case tx, rx,rx enable is enough, and also shall...
Hi everybody!!!
I am making a project which use NUS service and I have confuses in connection mode:
when the central and peripheral do not have data to transfer...
Hello, my question is pretty clear i guess. Is it possible to schedule advertising of 2 different packets on the same chip ?
The way i see it, it should be possible to...
Good morning, I´m trying the example of this post (ble_app_template_with_pstorage_operations_nRF51DK.zip). I have SDK 8.1.0, softdevice 110 and nrf51-dk.
The source works...
Is there any clear documentation to add an external memory to the nrf51822 to store some sensor data. How is the performance and stability when interfaced this way?
Dear all,
I'm working with nrf52832 and SDK 11.0.0.0.
I want to upload SD 2.0.0-7. Download results OK but,
