Starting with u-blox ANNA-B112

[vrba.vojtech]

I ask you for help with programming Bluetooth module u-blox ANNA-B112. It is based on nRF52832. I have already installed Keil MDK5 with nRF52832_xxAB package, soldered the module to DIP adaptor and I have tried to connect to the module via USB programmer CMSIS-DAP (connected VCC to 3.3V, GND and SWD pins).

But I am experiencing problems - I am not able to flash compiled program using this programmer, it does not communicate with the module. Could you please give me an advice? Should I use another programmer (eg. ST-Link, ULink, J-Link)? I have already programmed STM32, ATSAM and AVR MCUs, but I have no idea how to start with nRF52.

Thank you very much.

Have you triple-checked the pin-out?

I suggest you use a J-link as that's what we use in-house, on our DKs, and as a part of our PC app toolchain. I believe the nRF support in the ST-link is some third-party stuff that we do not know the quality of. A U-link should work given that it has support for the nRF52832.

It is now working. Only with J-Link programmer, programmers such as ULink, ST-Link and other are unable to connect using SWD...

Thank you!
