Hi,Hardware used: STM32L152RE nucleo board and SPSGRF-868 moduleTechnology and OS: 6lowpan and Contiki.Example used: UDP-sender and UDP-receiver.SDK used: Sub-1 GHz RF communication software expansion for STM32Cube I'm developing 6lowpan network usi...
Hi,I want to program a connectionless observer to scan events, but the hci_le_advertising_report_event() callback isn't called. I have followed the steps of programming manual PM0269 for configure the modular configurations to work as Broadcaster + O...
Hello, My name is Jean-Pierre Key. I am the owner of a tech startup, and the ST60 contactless connectors, have caught the eye of myself and of my engineer. We were wondering, if we could procure some information, to facilitate a design for a device t...
If changed char length 450 to 140 now every thing will be fine. but when i put char length 450 or more than 140. It will return 0x48 error value.The paramerters i was passed, these are ret = aci_gatt_add_char(chatServHandle, UUID_TYPE_128, (Char_UU...
I am designing some firmware for a BlueNRG LP (355MC) based device with several sensors. At certain points in the device's processing/lifecycle, I need to turn off the BLE and/or radio to conserve power. In fact, I only need the device to have BLE co...
Now and again, following power-up, we find the STS1TX in our product in a state where we cannot interface with it. The SPI and GPIO lines are outputting ~2V levels, so no commands can be sent.Typically, cycling power may allow the chip to initialise ...
Very standard "app note" circuitGood decoupling. 2.8v switched supply railXO is up within 350uS of startupDevice is programmed about 100uS after detection of the "reset OK" state
Hello,I'm doing some development work with an STEVAL-IDB011V1 dev board. I'm targeting very low power and so I would like to verify the numbers listed in the datasheet.In DEEPSTOP mode at room temperature, I am expecting something around1 μA of suppl...
I am trying to acheive a BLE Mesh system where no network data will be stored to NVM, i.e. system will need to reconfigure on every reset.The network consist of one PRV and a handfull of LPNs, the LPNs will be mobile and will therefore enter and leav...
