Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...

Hello,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...
I downloaded the source for the Android UART app, hoping to hack it into something I can use to test my gadget. But it's incomplete: it fails with the message:
Missing...
I have 3 short questions:
Does S120 support or will support swiching over BLE and Gazelle like S110 does?
Will be able in future to be connected to a BLE...
Hi,
If I want to send data(400Bytes) to client(phone),I must use sd_ble_gatts_hvx to notify client. Is it right?
Every time I notify 20bytes until the end, is it right...
Hi,
I understand that the available RAM on the nRD51822 is 16k. How much of that space is reserved for the transmission/ reception of BT packets?
Thanks,

I've got something put together akin to the ble_lbs demo which uses a custom service. In fact, it's merely the LED part of that ble_lbs service, but on custom hardware. I...
Hi,
I have just received my nRF51822 based development platform. I bought nRFgo, nRF51822DK and nRF51822EK. However, I am only playing with the Evaluation kit to gain some...
Hello,
I try to modify the advertising initialization to advertise only my custom service (BTS_UUID_SERVICE ). Objective is to hide (just during adv) others sig services...
Hi,
where could i find detailed current consumption and timings (wake-up, rx, tx, power down) in connected mode for RF51822, in order to compute average current value for...
My device :
nRF6310 Rev 1.4(nRF6700)
nRF2722 Rev 2.2
I will use those devices to test RF communication between nRF2722 and nRF51822. Software environment is...
Hello,
I am playing with the s110 ble_app_proximity example.
As I do not want to store info in flash, I do not want to use the bond manager, that stores data in flash...
I'm currently using a combination of the GNU ARM Eclipse plugin and the unofficial pure-gcc Makefiles to build my nRF51822 code. The build works fine with the pure-gcc Makefiles...
Hello everyone,
I want to create a real-time wireless sensor network. There are 8 sensors in the net. I use two nRF24LE1 as receivers to recieve the datas stimultaneously...
Any idea what the max SPI slave clock frequency is on the nRF51822? The product specification (page 46, v2.0) says the max SCK frequency is 2MHz, but I was wondering if any...
