Hi Experts,
I modified a DFU bootloader from SDK 9.0 for nrf51822_xxAA chip. However, I encounter code size overflow problem when building it.
I found the ROM1 configuration...
Here are my 2 scenarios:
I need a radio chip that will be used to form a mesh network in dense bush with each node up to 150m apart. Is this possible?
I need the...
Hi all,

I've developed my BLE application that is based on nRF518822 and softdevice S110 v.8.0.0.
I've defined 6 services (4 with 2 characteritics each and 2 with 1 characteristic...
Hello,
I want to add uart debug support to the BLE DFU bootloader (nRF51822, S120, custom board).
Therefor I increased the possible size of the bootloader (start 0x39800...
Good evening and a happy new year to everybody.
Now it's time to work again, and I already stumbled about a little twouble while implementing a peripheral with concurrent...
Hey guys,
I'm designing an antenna for our open source sensor beacon, RuuviTag: http://ruuvi.com
Because we're using 1/4 wavelength monopole antenna, I'm considering...
for ble, scan of central device can get the RSSI value of the advertising device, but the inquire can not.
Is it right?
what's the different between them?
Hi,
I have made custom nrf 51822 board, I don't have LFCLK crystal i.e, 32.768khz. When i run ble_hrs example code in it , current consumption of my board goes to ~150uA...
Hi
In my application I need to transfer several paires of bytes to a slave device, and it's mandatory
for CS signal to go high between pairs. (This actually means I have...
