Hi Andhika,

It's ok to parse/interpret the command input inside the nus_data_handler(), it doesn't require much processing so the ISR will still be short. Other time-consuming or potentially blocking operations can be moved to the main loop.

Hi Vidar,

thanks for your respond yeah i found it, and i tried to rewrite it in main in the main loop but it doesn't work, is it safe to write my switch case in nus_data_handler instead? because i considering the existence of interrupt in the function.

Hi Andhika,

p_evt->params.rx_data.p_data inside nus_data_handler() points to the data buffer where the BLE message is stored.

Hi thanks for your respond but i'm having a hard time finding where the received data stored.

my idea is using a switch case, example if i send '1' from a phone i want the board gives me 'Hello',

other microcontroller that i used to work with has a variable or memory called sbuff where all the received data stored in.

do we have such a variable so i can easily used for my switch case?

best regard and happy new year

Andhika

Yes, it shouldn't be a problem. But you need to modify the example code. The documentation I linked to in my previous answer shows where received data is handled, and where the UART data is passed through to BLE.

hi vidar, yes i tried it but i still need the uart cable to read the message that send to the board

or i rephrase my question, is it possible send a schnittstelle via custon gatt and get feedback from the board which i can read on terminal i smartphone? like example i send 1 to the board and get feedback like 'Hello' that the board send via ble?

thanks for your respond

Hi,

Yes, please take a look at our UART/Serial Port Emulation over BLE example.
