https://devzone.nordicsemi.com/f/nordic-q-a/12120/nus-app-to-send-uint8_tHello, As far as I can tell, the NUS app sends a signed char of value -127 to 127 in decimal. Is there a way to use the stock UART application to send an unsigned byte of value 0 to 255? In other words, can I send a string such as : {0xDE, 0x02, 0XF5en-USTelligent Community 13Thu, 25 Feb 2016 13:39:32 GMThttps://devzone.nordicsemi.com/thread/45858?ContentTypeID=1Thu, 25 Feb 2016 13:39:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fc3d563e-dd37-4e8c-b4b6-098484ffe8e2seanbites<p>Ok thanks, I&#39;ll check that out :)</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/45857?ContentTypeID=1Thu, 25 Feb 2016 13:38:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e1816cb2-3b3d-488e-9c77-ea3c8b97fb42RK<p>The mobile application may only let you type in ascii characters, but the NUS service can send any byte from 0x00-0xff. You just write the byte, it sends it.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/45856?ContentTypeID=1Thu, 25 Feb 2016 13:36:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2033bb15-9655-4620-ba73-f1b8592d248dseanbites<p>To clarify: I&#39;m trying to send {0xDE, 0x02, 0XF5, ...} from the mobile application to a peripheral device. The mobile application can only send ascii characters, so the range of values that can be sent is very limited. Is there a way to send values from the mobile application that are not ascii (say between 0x00 and 0x30)? Hopefully without having to modify the mobile application. Thank you.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/45855?ContentTypeID=1Thu, 25 Feb 2016 00:04:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:74ec17fc-b319-4fd4-86e7-8b2fa9356424RK<p>They&#39;re just bits, you can interpret them any way you like, just cast the uint to whatever&#39;s needed by the NUS service and send it.</p><div style="clear:both;"></div>
