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...
I am try this at nrf51_sdk_v6_0_0_43681\nrf51822\Board\nrf6310\s110\ble_app_hids_keyboard
Firt I connect to Android device and keep one whitelist.pp_addrs and one whitelist...
The nRF24L01 dataseet V2 (the most recent I think?) states (p.23) that the nRF24L01 can operate on frequencies from 2.400GHz to 2.525GHz . The channel steps are stated as...
I am completely confused by the nRF51 UART. I'm trying to port code originally written for an STM32 (another cortex chip). There, I define an interrupt, enable the RXRDY or...
Hi,
I need to have two different interrupt handler for one pin?
For LOTOHI one handler and for HITOLO another handler, how to do that?
Here is what i did until now...
Hello Nordic and fellow developers
While implementing bonding into an application based on S130 I found it necessary to test on the role of a given connection. Different...
I am getting device id of peripheral on central and then getting it displayed on hypertermianl hyperterminal using ble app multilink perihperal code with multilink central...
Hi Everyone,
I have what I hope is a simple questions. I am creating a piece of hardware that will act as the peripheral to a central iOS app in regards to a standard BLE...
Is there any construction available in the SDK, to achieve printing functions, with an undefined number of parameters ? The classic example :
#ifdef CONFIG_DEBUG
#define...
Hello,
I've ready the final S130 spefication and it states that the advertiser is started as early as possible and that i runs asynchronously to all other roles. Now I...
Calling app_sched_event_put() from the NRF_RADIO_CALLBACK_SIGNAL_TYPE_START signal handler causes a crash due to the CRITICAL_REGION_ENTER() call inside of app_sched_event_put...

I have a simple nRF51822 BLE application where a voltage is read by ADC periodically, and several values are sampled and averaged. However, from time to time, I get another...
Hello All ,
I am working on nrf51822 with sdk 7.1.0 and softdevice 7.1.0 .Earlier my ble connection was working very good with no disconnection anytime unless i disconnect...
Now I'm working with MCP 3.9.0.
When any device is connected, characteristic default values are not 0's. Can they be initialized in any way? It is a little bit annoying when...
Is there a separate reference resign for the 1.8V of operation (as in case of nrf51)? Or it's implicit and the chip can be powered in range of 1.7V - 3.6V.
Thank you!
