I don't have a 32KHz crystal on my board (using the stock Rigado module) and power isn't an issue as the board is mains powered in operation, so I was intending on using the...
I found a alpha version of softdevice v3.0 (s132_nrf52_3.0.0-2.alpha.zip), and it supports MTU_SIZE > 23 bytes, but there is no SDK (current version is v11) supports it. When...
We have two nRF51822 chips with cleared contents in FICR, e.g. addresses 0x10000000 - 0x100000FF are 0xFFFFFFFF.
UICR works as expected.
Chips execute code.
Radio performance...
