before i write the flash, it has been erased.so ,its value is all 0xff.
when i write 0x00 to flash address 0x0001,the value read out is not 0x00 but 0x01,and the value in...
I'm looking for a way to use the nordic uart service ( devzone.nordicsemi.com/.../ble_sdk_app_nus_eval.html) from Linux using the native Linux BLE Stack (BlueZ). My application...
Hi,
I've created an application using the S110 experimental ANCS demo. I successfully implemented ANCS and then began to structure my application around it. At some point...
Hello,
In an ongoing company project we use a couple of nRF51 transceivers forming a beacon enabled wireless sensor network consisting of one base station and multiple...
I want to count clocks in order to implement a watch. I use the RTC0 as my time-base and count mainly with this device. As it has just 24 bits it would not last for long,...
Hi,
how long does it take time if i would wake up a nrf51422 rev2 (ANT and BLE) in deepest possible sleep mode ?
And how long does it tai if after wakeup it had to communicate...
I saw that the app_timer uses the SWI0. Could you explain what it does and what the advantage is compared to "timer_list_handler_sched()" calling "timer_list_handler()" directly...
Hi,
I am using the ble_app_uart_c example for the ble_central of SDK 12.2.0 to send data over UART to a nrf52832 based peripheral. When following the format as suggested...
i use sdk14.2 52832 as central , have bas service and myself service it have pair process , there are one change question. When I first burned the program, the bas service...
Hi,
I'm using Noble.js on a central RPi3 for DFU updates over BLE. The process is several times slower than doing the DFU over nRF Connect on an Android phone. I believe...
I am designing a NRF52 based device. One of the component , Crystal X1, EPSON FA-128 32.0000MF10Z-AJ3 used in the reference design is not available for purchase in online...
On the included Thing52 example, the LED fires m_ioext_osc_status_change from an interrupt. Eventually, when it comes to requesting use of the TWI this comparison happens...
I've noticed that if I call app_usbd_cdc_acm_write with the length set to any multiple of 64 the data will not show up on my PC until I do another write with a value that...
Hi DevZone,
I am modifying an CAN library for nRF52840 preview DK. In my project, nRF52 preview DK is working as a SPI master and Arduino CAN Bus Shield is working as a...
Hi,
I am developing a device using the PCA10028 Dev Kit
It is configured as a BLE Central, SDK 7.2, SD 120
I am starting out with the example "ble_app_hrs_c_s120_pca10028...
Hello
Ive implemented and modified the light_switch_example and now I want to change the tx_power(sd_ble_gap_tx_power_set(uint8_t role, uint16_t handle, int8_t tx_power...
I am writing a program that waits for button 1 to be pressed. once it is pressed for 5 second it will call the LED ON api and when button 1 is pressed again for single shot...
i want to know which example in the SDK of MESH is the fast way make a demo to show this functon: use our moble phone to control more LED in same time.
remark: every LED...
Hello, I ask a question about power_manager() which is internally called sd_app_evt_wait(). I want the program to enter power_manager () to stop waiting for the event to come...
Hi guys,
we have triggered one interesting state of fds module… This could be somehow connected to https://devzone.nordicsemi.com/f/nordic-q-a/27259/fds-data-corrupted/107629#107629...
I have a problem with upgrading bootloader on NRF52832 IC. We are in the middle of porting our own bootloader from SDK 8.1 to SDK 14, because we had to change BLE modules...
Dear All,
while evaluating low-power options in the context of wireless sensors, I've stumbled upon a strange behavior with the nRF52832 using ESB from SDK 14.2. Here's...
