Hi,We have assembled 10 Boards with LIS2DH12TR out of which only 6 Boards are working Rest 4 aren't at all working.we tried resoldering the sensor again and checked still the same issue.What would you suggest to do?
For battery management I using BQ25713Power profiles, which I tried is: 20V 1A (PDO3 default) and 20V 3.25 (also PDO3 manually configured on STUSB4500, this profile appropriate to maximum power of my USB PD adapter 65W 20V 3.25A)This problem exists f...
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...
