S2-LP transceiver, STEVAL-FKI868V1: it has a feature 'Automatic acknowledgement, retransmission, and timeout protocol engine".1. Does the acknowledgement automatically come from receiver?2. Does this feature automatic for S2-LP transceiver or it may ...
Hi,I'd be grateful for any suggestion what BT module supporting HID I should use to connect BT HID keyboard to the STM32. I see that many popular HC-XX modules support only SPP profile.There are some modules supporting HID profile but all the example...
Hi,I'm using HAL_I2c_Mem_Read(), too.And may I ask if STM32's I2C can generate wave like the following picture. I have tryed Mem_read() and any other function in i2c.c , but the bit following device addres is "0",which means "write" in I2c.eg.I want ...
I've bought two ISB042V1 and i want to send sensor Data trough the QI connection from the Rx to Tx. But i do not understand how i can write data from MCU1 into Rx device, and read out from Tx device into my MCU.
I have been attempting to use Silicon Labs Si443x/RFM22 ISM radio IC for over a week now with no success. My overall impression of this radio IC is poor. Lots of issues, erratas, and twitchy-spazz operation even under ideal conditions. So naturally I...
Hi All, Currently S2-LP only supports down to 433MHz, would it be possible to use a lower frequency crystal to achieve a lower frequency such as 403MHz?Thanks!Xarion
