Hi all,
I am new to Nordic semiconductor but I could be interessed by nRF9E5. To check if it could fit my requierement, I would like to know if it possible to configure...
Hi,
I am using ADC without external reference and no analog input in order to measure the battery level with a timer (code at the end).
I am also reading several ports...
Hi,
I'm programming the nRF51822 and save some user data into the FLASH by using pstorage_update . It works fine if I set system off mode, and wake it up. I can read back...
Hi,
I have been using nRF51822 with my Android app using Android's Bluetooth Low-Energy APIs.
In order to get more details, I am currently working on integrating the Android...
I'm looking at interfacing a typical Wheatstone bridge sensor to the nRF51822 ADC. This particular sensor only requires a mA or two for excitation and the output fits within...
When use the "nRFBeacons" app to update the info on my beacon the following happens:
Go to update tab.
Select "Connect"
Press "SW2" on beacon and see the LED begin flashing...
I am using s110 and nrf51822. I've set up up a long characteristic of 154 bytes.
Sending between 1 and 154 bytes works as expected.
Sending 155 - 160 bytes gets rejected...
As indicated in the PS, System On Mode idle draws only 2.6 uA.
Does this mean that if I install and active a timer interrupt, where the interrupt routine places the system...
Hi,
I am new to ARM development. We are thinking of ordering mkit for evaluating and developing a custom BLE service(profile) which sends data to BLE client (probably a...
Hello Everybody!
I have been working with BLE security and I have an issue with OOB setup.
I'm setting my nRF with the following:
m_sec_params.timeout = 30;
m_sec_params...

Yo!
I'm very concerned by what I hear about Bluetooth Low Energy security. According to this guy , who presented a paper on the subject at a USENIX conference last year...
Any experiences about analog sensor LM35DZ? I used this example: main.c
The LM35 data sheet says it will operate from +4V to 30 V supply. I'm use supply only Vcc pretty...
Hi all,
this is not a question per se but rather a warning to those who are attempting to debug Flash related operations with the SEGGER J-Link GDB Server (v4.84a for Linux...
I'm using API 2.1.3 and I'm having problems with SendData blocking forever at the end of a process. I placed access mutexes around each method call to the library, as well...
Dear Nordic Developer Zone,
I have modified the ble_conn_params.c file in order to be able to negotiate new connections speeds between IOS app and Nordic nRF51822 chip...
Hi,
Regarding the bond_info_store() routine, I am having issues where after several calls to this function (client pairing forget/reconnect), my p_bond gets corrupted. This...
Hi, I am developing a BLE application using SPI and TWI. (Using nRF51822)
This discussion is about my survey in development zone for future develop the TWI part.
I want...
I'm calling ble_bondmngr_bonded_centrals_store in response to BLE_GAP_EVT_DISCONNECTED as is the case in plenty of sample code, but when ble_bondmngr_bonded_centrals_store...
Hi Guys,
I have managed to get the BLE DFU demo service working fine (dual bank) on nRF51822 EK. I use a Linux Python program ( bitbucket.org/.../nrf51_dfu_linux) (with...
what is the detection speed, when the beacon
enters into a wall unit area? With their 868 beacon they can
detect in 0,2 seconds. Is the nRF51x22 in sleep mode and does it...
