I'm trying to design a very low power sensor that takes readings using ADC and SPI 200 times a second. I'm a bit worried by the current EasyDMA uses (1.1mA). As far as I can...
Hi, I am working on a project where I want to make one nrf51288 chip as central hub and connect that to a android phone and other salve nrf51288 .

Hi,
I have a code programming the nRF51422 development board to write to a Sharp Memory 96x96 pixel LCD screen using SPI.
Currently the code writes two numbers and a...
I've modified the ble_app_uart example by adding GPIOTE so that the transmitter sends a character to the receiver when a GPIO pin is toggled. This part is working well.

Hi,
I am working on my hardware product having nRF-51422 chipset. I just came to know from forum post that
nRF-52 chips will get arduino IDE support as standalone. I want...
Hi!
I've been using PCA10028 for a long time and I had some bricking issues but I've managed to un-brick it with "nrfjprog --recover" and everything would work again. ...
I want to build nrftoolbox app in android studio. I downloaded the zip file from the github website and also the required dfu library. I unzipped both the files in a folder...
Hi,
how is the new nrf_drv_twi supposed to be used for reading registers?
The sequence for that is pretty much industry standard:
> Device address
< Ack
> 0x00 (register...
I'm running the ble_hrs example provided on my nRF52 board. The thing is, I'm unable search my device using both nRF Master Control Panel and normal Bluetooth connection from...
I am using a central S130 softdevice in an nRF51822. I connect to a peripheral using sd_ble_gap_connect(&m_peripheral_address, &m_scan_param, &m_connection_param) . If it...
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:

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...
