we also produced self PWM for ADC wave form testing. when we stop transmission, we will get good waveform out, but when we starting transmission, output waveform shape is...
Dear Support,
I have some troubles with the Evaluation Kit for nRF51822 :
I use the broad as a central role with S120_nrf51822_1.0.0_softdevice.hex and example...
Suppose a nRF9E5 transmitter is set for continuous transmission on a channel.
A nRF9E5 receiver listening on that channel:
finds carrier and sets CD
finds address...
I will be deploying my nRF51822-powered devices into the field and the end user will not be able to have any physical access to, for example, power cycle the board. I need...
Hi,
We are using the ble_app_uart example in evaluation board to read data from some sensors and send it to the nRF UART V2.0 in Android 4.4. Every 20 ms I am trying to...
I am try this at nrf51_sdk_v6_0_0_43681\nrf51822\Board\nrf6310\s110\ble_app_hids_keyboard
Firt I connect to Android device and keep one whitelist.pp_addrs and one whitelist...
Hi,
I wrote some code that writes to the flash perfectly when BLE is not enabled but when it is enabled, some of the data are correct while others are either missing or...
Hello folks, I have modified the SPI Master Loop example from the package so that I could communicate with the ADXL 345 accelerometer. I use the "spi_master_send_recv()" function...
Hello,
I'm trying to retrieve data from a nrf51822-based board that supports the BLE NUS sevice (using the ble_nus Library provided for the uart communication example,...
Hello!
I've just started using the nRF51 dongles (currently having 5 of them) and I would like to test the GitHub mesh protocol . Excuse my lack of experience, but I am...
Hi,
I'm trying to load the ble_app_beacon application under C:\Nordic Semiconductor\nRF51822 Beacon v1.1.0\Source Code\nrf51_beacon\ble_app_beacon\pca20006\s110\arm_build...
Hi there,
Is there any way to resolve a BLE_GAP_ADDR_TYPE_RANDOM_PRIVATE_RESOLVABLE address without using whitelist advertising? If not, I guess I should implement the...
Hi,
As question "custom serial wire debug" date Jan 14 '14, I'm also interested in programming the chip from an other embedded chip (would fit our production process verry...
Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hi All,
I am using the nrf_udp_client example project in IoT SDK as the code base for testing the UDP communication.
For network topology, the nrf51-DK plays the role...
Hi everyone:
I have some question about nrf51822 power on sleep mode
in example ble_app_hrs have a "power_manage" function and it will make the system go into power...
Hello all,
I have a simple C++ application flashed to my device to operate the UART - every time I send a char from an external source, the device appears to reset - specifically...
Hello
I was wondering if it is possible to run to separate LP-comparators on the PCA10001? I've taken a look at the example code for LP-comparator in the SDK, and i was...
I'm using interrupt_handler.c for a bootloader without a softdevice from this source . Interrupt handling in the main app seems to work fine. But interrupts in the bootloader...
Hi,
In the nrf51_bitfields.h file, I can see definitions for two registers POWER_RAMON and POWER_RAMONB.
But I don't see this RAMONB in th nRF51 reference manual and...
hello, I bought one of these dongles on ebay www.ebay.com/.../201229095155
i was hoping to communicate to the nrf24l01 modules with my pc serially, but I can't get the...
