How can I send data more than 4bytes in BLE

[BEN_HB]

I followed this tutorial :Bluetooth low energy Characteristics, a beginner's tutorial

i am beginner to study BLE.

I wanna the answer Challenge 1:Why are you not allowed to write more than four bytes to your characteristic and how can you fix it?

i got data from sensor value through ble on my phone. but it can get only 4 bytes data.

Is that a homework question?

In general, there is no reason why a Characteristic should not allow writing more than 4 bytes.

So the reason must be something to do with the particular Characteristic that you've been given for your homework.

As we have no idea what that is, we can't help other than to suggest that you review your class notes and find the part where it explains how that Characteristic's size was set ...

Thanks your reply. It is not homework and I am not class. I study myself. '

I follow DevZone Tutorials.

here is the site:

 https://devzone.nordicsemi.com/tutorials/b/bluetooth-low-energy/posts/ble-characteristics-a-beginners-tutorial

there is the question. I also think there is no reason limited only 4 bytes.

maybe I miss something BLE structure.

I thought divide data what i want to send per 4bytes. but it is not answer i want.

Could you give me more help?
