Hello, I'm working with BlueNRG-M0.All is fine when I work with 1 little service. Today I need to implement lot of services and I'm stuck with the error 0x1F from aci_gatt_add_serv() function.My init is this:/*----- CODE -----*/ uint8_t SERVER_BDADDR...
Hi,I would like to use the STUSB4500L to power a battery powered application as well as talk to it over I2C, however since I'm running low on I2C buses I want to share the I2C bus with it and my other battery management ICs. From reading the datashee...
I'm starting a new SW project for a BlueNRG2 module and it's not clear what the currently preferred development toolchain is. I want to make sure I'm not using deprecated tools.The BlueNRG2 will be used as an application processor (i.e. not connected...
Hi, I am making a USB power hub which support USB C Power delivery. There is a upstream USB C which support Sink and Source role:if there is a DC input, this is a Source, STUSB4700 is enabledif there is no DC input, this is a Sink, STUSB4500 is ena...
Also, will the VBUS_EN_SNK pin get asserted (pulled low) in this case, allowing the power path to enable 5V from the USB 2.0 cable to power the device?
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...
