Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
I am trying to set-up power management for a USB charging point using an STUSB4710 (i.e. dropping the allowable current for certain PDO when less power is available). My main issue at this point is that the I2C commands required to get this set up ar...
Hello, I'm developing a project on a NUCLEO WL55JC1 board. I require Bluetooth communication between my board and some sensors, so I'm implementing the BLUENRG-M0A module and the X-CUBE-BLE1 pack. Similarly, I'm using the SampleApp example as a base....
Can you tell me is the SIM7022 is also compatible with the ST4SIM-200M. Best regards Peter Jonkers
Hello,I'm using bluenrg-lp with BLE stack initialized for Rx only, I set to GAP_OBSERVER_ROLE and the observation procedure is stopped, I'm trying to enter in sleep mode POWER_SAVE_LEVEL_STOP_WITH_TIMER based on example code : WakeupSourceConfig_Type...
I am designing a usb type-c charger. I want to use 2 microcontroller and 2 STUSB4710.Type-C Output will be 20V 3.35A 67W.I want to do power management between these USB Type-C outputs.I have questions. Can you please answer them? 1. Are there any I2C...
Hey team,I wanted to check if there is any bridge IC that can convert parallel camera interface data to USB 3?And/orDo we have anything that can convert MIPI CSI-2 to USB 3? - again for a camera IC.Thank you for your help!
Hi evryone,I've been trying to work on Zigbee communication for a while now, so far I've just learned how to read and write attributes. Now I'd like to try to learn how to use cluster Identify and groups, but I dont understand several thing, so I nee...
Anyone in STM have a datasheet for a P7C806 chip? Its part of a 2 wire bidirectional digital serial communications link, so may be a level shifter or line driver? Thanks.
Hello st community, I'm trying to use the BlueNRG-355 in deepstop mode without timer, to wake it up with an I/O. I used function from Power Save Modes project from the NavigatorHAL_PWR_MNGR_Request(POWER_SAVE_LEVEL_STOP_NOTIMER...);It does not enter ...
I have a BLE application running on BlueNRG chip. In one moment I want to pause Bluetooth communication and put the device in the deep sleep. It should wake only by GPIO interrupt. Then, the BLE stack should be active again. Unfortunately, if I call ...
