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,
Edit 25 Dec '15: Rewrote post for better readability:
I am trying to modify the dual bank DFU bootloader example to work on our custom board that uses a nRF51822QFAA...

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...
Hi
I want to know why flash memory access should be scheduled in between the protocol radio event?
is there any relation between the flash access and radio opeartion physically...
