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'd like to check the battery level in my BLE device, and I can set a timer to handle the checking, however this means that Timer 1 would need to powered up, and hence...
Hi,
The situation: nRF51 has established a connection with the iOS/Android (custom made)App. The nRF51 goes out of the Bluetooth range. Eventually, the Bluetooth connection...
I have looked around but have been unable to find doc explaining this. If there's something around, I'd truly appreciate a pointer.
I have an existing (solar powered) device...
Hello,
i'm searching for informations about calibrating the SAADC of the nRF52. And i have read here: Link
For nRF52, there are no calibration
values that I know of...
Hi Sir/Madam
I wrote a small program for low current verification on nrf51822 development kit with starter mother board.
The program is based on "blinky_example" project...
Hello to all,I have developed a board using the NRF51822;
Currently I am using SDK v11, S130 v2.
I have a problem in my bootloader, since bootloader_app_is_valid (from...
Hi, i want to jump from my app to the bootloader, i used the function
void bootloader_app_start(void)
{
vMBt_eStopAdv_Exe() ;// Stoping the BLE ADV

I have a question about when the application is erased during serial DFU single-bank update:
According to the S110 Serial HCI documentation , the serial update packets...
Hi,
I just purchased an nRF51 sniffer. I have set everything up as per the UM. When I invoke the sniffer application, it says scanning for devices, but nothing shows up....
Hello.
I'm investigating how bootloader works (bare minimum), especially how it brings control to an application (already flashed at 0x1B000, s130 SoftDevice also present...
Hi,
I'm creating a simple SPI bootloader without SD for nRF51822 based on this post
The bootloader is connected to Freescale 22F through SPI and it will be without any...
Trying to build the examples for the NRF52 and ant. I have the latest download of SDK11 (nRF5_SDK_11.0.0_89a8197)
It looks like paths are broken as well as missing the ant_interface...
Hi,
I want to communicate with other chip on UART.
the chip on other end requires AT(CR,LF) command to start communication over UART.
UART is setup correctly, but it...
hi guys,
So i made a board with an nrf51822 chip (256kb ) and some sensors + RTC(realtime clock).
The RTC will generate an interruption every 1 minutes. During the interruption...
