Hello,I have build a custom pcb and I am using the BlueNRG-M0 module and the STM32L162VET microcontoller. My main goal is to be able to transfer data via bluetooth to a computer.To get starter, I tried to generate the VirtualCOMPort example that is a...
HiRegarding the P-NUCLEO-USB002, the schematic available in the resource section of this product does not seem to match at all the product advertised. The file is named MB1303 in the resource list.The file downloaded is namned MB1136.The P-NUCLEO-USB...
Hi together,I'm using the NUCLEO-F401RE and NUCLEO-IDW04A1 trying to connect and publish to a MQTT Broker. Therefore i've edited the example HTTP_Request. Connecting to my WiFi-AP is working fine, but connecting to the Broker does not work. This is w...
In the case where USB power is first applied and a 20V contract established, the STUSB4500 would enable the power path to Vsnk as per usual. Then assume a 20.9V (for example) secondary power source is applied to the Vsnk output (say from a wall adapt...
Hello,I'm working on extrem low power radio with S2-LP transceiver. To obtain a very low consumption in rx mode i puted it in sniff mode. My design has external TCXO reference and when i left it always on all work fine, but if i set gpio to switch of...
In Spirit1:SpiritRadioGetChannel() is flawed:uint32_t SpiritRadioGetChannelSpace(void) { uint8_t channelSpaceFactor; /* Reads the CHSPACE register, calculate the channel space and return it */ g_xStatus = SpiritSpiReadRegisters(CHSPACE_BASE,...
I'm a bit confused regarding some nuances of the BlueNRG-2's BLE characteristic value write procedures' functions & events. Below is my understanding with a few questions.Bluetooth Core Specification v5.2 | Vol 3, Part G; 4 GATT Feature Requirements ...
I'm using a spbtle-rf to scan for BLE beacons. I get the LocalName of the device scanned and its hardware 'MAC' address using either aci_gap_start_limited_discovery_proc() or aci_gap_start_general_discovery_proc() but I can't find a way of reading th...
