Hi.
I bought an nRF51822 from aliexpress, it happens to be C0 (revision 1) chip. Is it still possible to develop software for this version of chip? I used arduino and platformio with revision 2 (softdevice110 v8.0.0), but on rev1 it didn't work, first problem is the RTC1 cannot be started, counter register is always 0.
I searched on the internet, I found that I need SD110 v5.2.1 and SDK v4.4.2. I found softdevice but SDK is nowhere to be found. Can you provide the SDK or point me where to start with this?
