This blog is to give a demo how to scan the ble advertiser and show the RSSI and MAC address in sorting order. Basically, I used the demo firmware ble_app_blinky example and added the observer role (passive scanner). static ret_code_t scan_init(dm_ble_scan_t * const p_scan_ctx) { VERIFY_PARAM_NOT_NULL(p_scan_ctx); /* We expect better performance when using extended advertising/scanning. … Continue reading BLE Scanner with RSSI and MAC Address
This blog is to show how to add the scan request filter on the BLE advertiser. In BLE (bluetooth Low Energy), basically, it has two difference modes on the scanning mode. On the BLE observer, it can be either passive scanning or active scanning. If the observer plays as the active scanning, it would send … Continue reading BLE Scan Request Filter Demo
This blog is to show how to list all the COM ports on the terminal by using the pythons script. If you connect multiple devices on your PC, you would like to list out all the COM port information. Basically, you can find at the device manager in the windows 10. You can also use … Continue reading How to list out all connected COM Ports on Windows 10 through Python Script
This blog is to describe how to configure the Segger Embedded Studio to support the UTF8 coding inside its IDE. What is UTF-8? UTF-8 is a variable-width character encoding used for electronic communication. Defined by the Unicode Standard, the name is derived from Unicode (or Universal Coded Character Set) Transformation Format – 8-bit. UTF-8 is capable of encoding all 1,112,064 valid character code points in Unicode using one … Continue reading How to support the UTF8 on the Segger Embedded Studio
