UTF8 encoding in NCS

[Aniket95]

I want to convert raw hex bytes to utf8 format. The nRF5 SDK supported this with help of ble_srv_ascii_to_utf8() api. Is there something similar api available with nRF Connect SDK?

Hi Aniket,

Do you need to convert raw UTF-8 encoded hex bytes to UTF-8, or do you need to convert ASCII-encoded bytes to UTF-8?

If your input is in ASCII, then it is already UTF-8 encoded, because ASCII is a subset of UTF-8.

Hello Hieu,

Basically I need to convert hex bytes to ASCII and send it over BLE. So if I have 0x45 it should be represented as E. So I am wondering if there is any API exist for this in NCS.

Hi Aniket,

If it's ASCII, can't you just treat your string into a uint8_t array?

What is the type of your string in the first place? How are you handling it? I always handle simple ASCII text string as uint8_t array from the beginning, so I cannot really imagine what you want.

Hi Hieu,

I am handling it as an uint8_t array. Anyways I believe the problem was just about representation of data on nRFConnect app. I just named the characteristic, changed the format and it gave me the expected result.

Thanks for your help though
