Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hi,
I see that the nominal deafult rampup time is 140 us in NRF52.
However, I'm measuring it with logic (via GPIO+PPI) and I get 129.4 us.
Why there is such a difference...
Hi, I received an e-mail about the new nRF52840.
Nordic Semiconductor has today released the new nRF52840 multi-protocol SoC

I have seen thread related to this question such as this and this and I am aware that spikes happen due the automatically controlled refreshing mode of the DCDC...
Hi,
I am working on ble_app_uart_c example provided in SDK12.3.0 with S130. I tried this example on PTR5518 ble chip but suddenly device goes resetted every time.I am printing...
I'm finding rather high power consumption developing freeRTOS on the nRF52. I have it found that it appears Task's are suspending properly on the main BLE thread (copied from...
Setup
I was just looking through the code in the HIDS module in more detail, now that I have built a few demo HIDS apps I want to make sure that I understand the HIDS module...
Hi,
Is there any other define to change than SERVER_COUNT in main.c of client's light control in order to run the example with only 1 client and 2 servers (instead of 3 servers...
I cannot get the output from the is the example the UART buffer gets filled but there is no output to the tty.
The interrupts seem to be set, but I don't see the interrupt...
Hi
I am using nrf52840 for indoor positioning application based on RSSI. I was wondering if somebody has a tip how to calibrate the nodes before doing the experiment.
Hi,
I'm using sdk12.3.0 ble_app_uart.
My problem is BLE connection.
Sometimes(almost 50%)I tried to connect BLE but fail and I have to connect again.
I don't know...
Hi, I'm contemplating ways to drive a small RGB LED matrix with the nrf52832 in a really space-tight project. Ideally without any external components. I'ts maybe around 40...
