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 have an application that requires watchdog to run continuously. And from application I have code that jumps to the bootloader without device resetting using bootloader_util_app_start...
Hi,
Side effect of adding a LFCLK of 32.768khz with 90k ohm ESR oscillator? where as data sheet recommends Max value of 80kohm.
Side effect of adding lower drive level...
Hi everyone,
I activated softdevice writing protection with nRFGoStudio (i.e. so that the softdevice can not be overriden). How can I deactivate that again so that I can...
Just to make sure: Will The spi_master_send_recv return when it is done writing and reading, or do you have to have some event wait functionality listening to SPI_MASTER_EVT_TRANSFER_COMPLETED...
I was playing around with the gpiote example under exaples/peripheral/gpiote. The example uses a timer, ppi, and gpiote to blink an led. By default, the app uses Timer 0 and...
Hello.
How to write custom firmware updater, which:
Takes new firmware from other device on SPI or I2C bus.
Writes it to flash ("bank1" at 0x1B000, or...
Hi;
I'm studying on SPI communication at nRF51822 (not DK) but i could not find the pins for spi communication, i read at somewhere SPI is only used at DK(developer kits...
hi
i'm using the nrf15822 beacon for an application of communication on arduino
I just would like to understand how i should start to stream my data using the beacon beacause...
Hi all,
I am using S130 in scanning mode and I would like to list the devices that are currently advertising by their friendly name. I have access to p_ble_evt via BLE_GAP_EVT_ADV_REPORT...
Hi,
I usually use electronics.stackexchange.com/.../15143 approach for decoupling capacitors and until now I had much better EMI performances.
I make sure that tracks...
We would like to reduce the attribute table size a little to increase free RAM. Are there any guidelines explaining how we can judge how large the table needs to be for a...
I compile SDK7.2 example hrs in "experimental_s110_with_dfu" by eclipse,
and I download softdevice & bootloader by nRFgo
then i use master control panel to DFU the hex which...
In the nordic documentation it mentioned that in the init packet we can write list of supported softdevices so that if one of that matches it will start the dfu. But in Signed...
Actually, I'm not good at using English. So I'll try to struggle to type this question...
Sorry, Last week. My boss gave me a Nordic Mouse to develop some embedded one...
