We are developing low power BLE device , for smart watch ,we need example codes for BlueNRG-1 , for RTC, advertising content,and etc, can you please tell us where can we get from STM website.Regardsshreyas
Good afternoon,I've found few information about the available memory to use as for the GATT service in the BlueNRG-ms.I have a GATT service defined and I want to know if it fits in the BlueNRG and,if not, how much I have to reduce it For the second, ...
I am issuing the commands from AN4683 section 3.2, and the AT+CFUN=1 command times out without completing. Would there be example C code somewhere that can perform these steps with success? Thanks!
Posted on June 05, 2018 at 08:51Hello everyoneI am confused by documentation of BlueNRG and various description of exiting from WFI for Cortex-M0.What is going on when BlueNRG-2 is woken up from deep sleep by external gpio pin?Is the program continu...

Does anyone here uses SPBTLE-1S Bluetooth LE module? All the other modules from different manufactures and developers have at least -90 dBm and usually around -93 dBm. What's wrong with this module? Also datasheet of it is just awful: a lot of missin...
Posted on June 26, 2018 at 08:54I'm using BlueNRG-2 in Network Coprocessor mode over the SPI interface. After establishing a connection with my device, how can I tell if the remote device supports Data Length Extension?I've experimented with the AC...
Using BlueNRG-2 in Network Coprocessor mode with 2.1 FW. ATT_MTU = 247, max PDU = 251When using coprocessor mode, commands and events are sent as packets over the SPI bus. One of first parameters in a packet is the length of the packet (without the...
