CC2530 Development

[CBismark]

Hi,

I'm not Sure this is the right way to contact you, but I founs no E-Mail or any Other contact Information. I have a General zigbee question and you seem to be very versed in all Things zigbee.
Can you please guide me in how to get started with developing my own zigbee sensor? Let's assume I want to base it on the CC2530 SoC, which seems to be popular (e.g. Used in Sonoff Sensors). Do you have any experience in programming Software for these Chipsets? I assume I would need to purchase a license of IAR Studio (damn expensive)?

Hope you can help me with These questions. If not, just remove or close this question.

Kind regards,

Christoph
