I need to send data PIR motion detector sensor to the master controller in my motion detector network.
Can I get away with just one of the nrf51 chips and my PIR sensor...
We're trying to decide at what voltage we should run our nRF51822 on the next revision of our board. To date we've been doing fine at 1.8V. The current drawn on a 3.7V lithium...
hi, i made ble app including bootloader using nRF51822 (s110), sdk 6.1.0
when i use sd_nvic_SystemReset() function in app, it erase app's pstorage.
But i want to preserve...
Hi,
I use S120 as central device and I need to handle multiple connections.
However S120 works quite unclear to me.
If S120 doesn't reply to BLE_GAP_EVT_CONN_PARAM_UPDATE_REQUEST...
Hello ,
I am trying to develop an application using the S130 soft device using Keil MDK v5 Lite. I have came to know that it is not possible to generate a code size greater...

Can you...
hi,
I am trying to develop a network of ble devices.i want nrf51822 to function as a master and slave( not necessarily simultaneous). For that i need to develop a custom...
Hello,
Firstly, I just begun with BLE and I am trying to program nrf51822 to read the sensor data through TWI (I2C) connection and send this reading to the central device...
I have tested the ble_app_proximity sample firmware on nRF51822 eval kit and also on my custom board.
Everything, regarding the used services seems to work as intended. However...
We have an application in which it would be nice to change the supply voltage for our Nordic module (nRF51822 running the Soft Device) depending on which other modules on...
