we also produced self PWM for ADC wave form testing. when we stop transmission, we will get good waveform out, but when we starting transmission, output waveform shape is...
Dear Support,
I have some troubles with the Evaluation Kit for nRF51822 :
I use the broad as a central role with S120_nrf51822_1.0.0_softdevice.hex and example...
Suppose a nRF9E5 transmitter is set for continuous transmission on a channel.
A nRF9E5 receiver listening on that channel:
finds carrier and sets CD
finds address...
I will be deploying my nRF51822-powered devices into the field and the end user will not be able to have any physical access to, for example, power cycle the board. I need...
Hi,
We are using the ble_app_uart example in evaluation board to read data from some sensors and send it to the nRF UART V2.0 in Android 4.4. Every 20 ms I am trying to...

Hello,
I am trying to work with the nrf51sdkv10 and trying to install arm-gnu-gcc toolchain on my MAC-OSx (El-Capitan). I downloaded the 4.9.3 version and installed in the...
For nrf51, the current consumption is more than 1mA when GPIOTE is used since 16MHz clock is always on. Is this fixed for nrf52? or nrf52 still has the same level current...
Migration document is great - I'd be lost without it. I'm just trying to be sure I understand the two changes for "GATT Server Authorizable Write Commands" and "GATT Server...
Hi,
My S130 based BLE implementation, when scanning, seems to receive BLE advertisements out of order, when the traffic is high. I wonder why. Could it be so that the callback...
Hi,
I would like to misuse the SDK by creating an communications systems based on advertising. From several Q&A posts, e.g. this one ), I understand that the current S130...
Hi,
I am writing an application on top of NRF51, using a S130 Softdevice. I wonder about the concurrenceness (?) of the code I write, and especially if I need to use critical...
How do I make sure, the GATT server running on the BLE peripheral client connects only to a specific app based central/GATT client app, which has been authenticated via web...
Hi everybody!
I am working on ANCS and I found a problem that: At the first time I connect my Iphone to the dev kit, the pair request appeared on the Iphone. If I ignore...
Hi,
I have been having a lot of problems communicating with an Atmel SAM D09 as a slave, and an nrf51422 as a master.
I seem to have two problems, hopefully solving...
Hi all,
I design the kb based on the SDK6.1 and SD7.1 with 51822, and doing the PTS certification now, but meet some problem on TC_CON_BV_01_C, ATT Write error, such as...
