I want to control GPIO toggle by PPI. Timer1 is in timer mode. CC[0] is 1000, and CC[1] is 8000.
I use compare[0] to toggle gpio18 by PPI. I also want to use compare[1] to...
Hi,
I use two evk board to connected and test the uart serialization sample(ble_s110_serialization), one is ble_app_hrs and one is ble_app_connectivity. But I have one...
I am getting get BLE_EVT_USER_MEM_REQUEST and BLE_GAP_EVT_CONN_PARAM_UPDATE event, when writing to ble device, sample code did not handle these event, and seems no document...
Hello:
Why do I erase SDK5.2 version of flash and read not, in SDK4.2 can. I tested nrf51_sdk_v5_2_0_39364\nrf51822\Board\nrf6310\flashwrite_example is a good example.However...
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...
We are calling nrf_pwr_mgmt_run which in turn calls sd_app_evt_wait. We set a timer with the app_timer code to wake us up. I verified that the handler is called. However sd_app_evt_wait...
Hi, I want write code on rust, but build system of nrf sdk for nrf5340 too hard for creating bindings, so I decide to create own HAL on rust and embed it in C with BLE stack...
Hello,
I am working on a project that I built using the nRF52DK and then created a custom PCB. The software I wrote works on the DK with a breakout board for the RTC and...

Please find attached several fixes for bugs / incomplete protocol implementation in the MQTTSN stack that we have identified for inclusion in future versions of the SDK. ...
The Thread SDK is pretty awesome! :) However, It does has a bit of a learning curve for me because it only uses UDP instead of TCP.
While searching I found an MQTT variant...
We're developing on a custom NRF53 board. With the I2C bus disconnected from all peripherals, but with external 10k pullups connected, we get the following waveform when attempring...
Hello,
We are working on a research project in Sheridan College to create an indoor positioning system using BLE 5.1’s Angle of Arrival feature. We noticed that nRF52833...
Hi,
I am using the nrf52840dk trying to connect my bike power meter over ANT+, to then forward data to cloud (will be using the nrf9160dk and then the thingy91 once I get...
Dear Support,
I'm evaluating a tiny BLE chip that we can do:
reading multiple three SPI sensors: pressure sensor, accelerometer, and FRAM.
So with your BLE chip...
Hi,
Using 52833 it seems that sometimes the radio quits responding, ie, it is in NRF_RADIO_STATE_DISABLED state and there is
no obvious way to get it out of that state...
Hello,
I'm trying to program the ble_app_uart example program from SDK 17.0.2 in Segger Embedded Studio using softdevice 132 to a custom PCB (with the nRF52832 chip) using...
Hi,
I am using nrf9160 to handle the MQTT protocol and collect the data packets from another microcontroller using the UART interface.
Sending the data to the server using...
