Can you advise a hardware and software programmer for  nRF51822  ?

best regards

Personal preference is using SEGGER j-link, since Nordic provide the command line tool 'nrfjprog' to program all nRF5 based devices using it:

"The Flash memory however is what you need to program not the core processor" oh really? Where did you get that? Do you know that it's the processor that you talk to when programming the flash? :)

Mojo is right, it is not the core.  The core is the same among all silicon vendor except each vendor uses different flash chip hence the require driver for each one.  For instance, same Cortex-M4 on STM32 or NXP do not program the same.  You need to use the right flash algo to flash each.  If you want to know more, look in the datasheet of each one and look at the core datasheet on ARM and look at the OpenOCD source code where you can find flash algo for each vendor.
