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,
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...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
Hi,
I'm using nrf52 dk(PCA10040). I want to disable the SAADC between readings to save power. I am calling the function nrf_saadc_disable() to do so. It seems to disable...
Hi,
I am having some trouble to make NFC Tag emulation working with "ble_app_hrs_rscs_relay" example application in the nRF5 SDK v11.0 on a PCA10040 board. Actually I did...
Hi all,
i have a little problem with the #define NRF_LOG.
I have this warnings, and i don't know why.
Warning[Pg004]: macro parameter " VA_ARGS " is used in both expanded...
Hi,
I would like to generate PWM waves with on/off period as low as 10usec.
How to stop the PWM and restart it? I tried this but does not stop the PWM:
void pwm_start...
I am trying to advertise my eddystone UID,TLM and URL frame on advertisement. Here by board is in peripheral mode.
I used radio_notification_init() function where i have...
Hi
We are developing software for the nRF51 with Keil under VirtualBox. Previously we used the PCA10000 dongle with the Master Emulator and MCP without issue. Now, with...
It seems like there are several asynchronous things that happen and it's unclear what had proprioty over each other. I assume interrupts asynchronously interrupt everything...
Hi,
I use the nrf52 dk(PCA10040). When monitoring the current consumption of the advertising with the DCDC enabled, we see some current spikes. Why?
Here is two screenshot...
I modified the code of ant_background_scanning_s212_pca10040 to make it works with s310 on nRF5144 xxaa.
The code works fine, but loose a lot of RX packets (more than 80...
Bluetooth device directional broadcast (set my mobile phone Bluetooth device address), I open the phone Bluetooth, will automatically link if you can not automatically connect...
Hi,
The samples for using list are BUFFER = 4, but it does not specify is that is the only size that works, and what value do you place on NRF_SPIM0->TXD.LIST
In my...
Here is a little background.
I have been developing a product based on the S130. I used the device manager from the S120 device since version 0.9 alpha. I was able to build...
Is there a mechanism to notify the application when a client reads from an attribute? For example, I have a large attribute buffer (100 bytes max) with a default MTU size...
Hi,
We are implementing a device where we need to use BLE and PWM. For generating PWM we use app_pwm library. To decide on the number of cycles of PWM pulses, we use a separate...
