nRF52840 Adding Characteristics Tutorial Challenge Question

[Soojin]

Hi!

I've been trying out a tutorial about adding custom service and characteristics 
( https://devzone.nordicsemi.com/nordic/short-range-guides/b/bluetooth-low-energy/posts/ble-characteristics-a-beginners-tutorial )

and in between, there were some challenge questions I couldn't solve. 

Challenge 1:

1. Try to write a single byte to the characteristic. E.g. '12'.
2. Try to write four bytes to the characteristic. E.g. '12-34-56-78'.
3. Try to write five or more bytes to the characteristic. E.g. '12-34-56-78-90'.

What happens? Why are you not allowed to write more than four bytes to your characteristic and how can you fix it?

Can someone tell me how to fix my code to write more than 4 bytes???

Always thanks for all your support.

Oh I just figured it out by myself!!
I accidentally forgot to change the number in uint8_t value[4] to the number of bytes I want:)
