https://devzone.nordicsemi.com/f/nordic-q-a/5834/which-soc-i-needAm trying to setup a module where I need to send the Serial port ( say from printer/peripheral COM) to a BLE Peripheral/Central Module. Not sure which SOC or combination of them would help me achieve. New in the domain so would appreciate help withen-USTelligent Community 13Thu, 05 Mar 2015 07:29:11 GMThttps://devzone.nordicsemi.com/thread/20382?ContentTypeID=1Thu, 05 Mar 2015 07:29:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e2b5dbbb-2188-40ff-b14a-b4e4572a5c5aAsbj&#248;rn<p><a href="https://www.nordicsemi.com/eng/Products/Bluetooth-Smart-Bluetooth-low-energy/nRF51822">You should have a look at the nRF51 family of products.</a> This chip will enable you to do what you are describing, just ensure that the voltage level entering the nRF51822 is within range from the serial port. You may need level shifters.</p> <p>There are UART <a href="http://developer.nordicsemi.com/">examples available in the nRF51 SDK</a>. Just as a reference, <a href="http://developer.nordicsemi.com/nRF51_SDK/doc/7.2.0/s110/html/a00061.html">here&#39;s a link to documentation about it as well.</a></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/20381?ContentTypeID=1Wed, 04 Mar 2015 22:18:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b812d1bc-4b6f-4bab-9f56-ec7ff6476d82Nguyen Hoan Hoang<p>The nRF51 series has UART interface. There are UART example code from the SDK.
