We are using the procedure defined in AN4491 to upgrade BlueNRG-MS firmware from 7.1e to 7.2c. Blue_flag erase (aci_erase_blue_flag), flash erasing and programming works but the aci_reset_blue_flag step is failing with response “0x4A: Blue Flag faile...
How to transfer audio files from the phone to a (BLUENRG+STM32+SDcard), without using additional software on the phone? I'm not sure, but I need an FTP profile. I need to realize the transfer of a sound file using the built-in Android / IOS functions...
I will attach you the circuit.It was just made looking at the datasheet and its pin configurations.Please go through the circuit and let me know for any modifications.Thank you.
Hi,I have a BlueNRG-MS connected through SPI to a STM32L476 like that implemented on ST SensorTile board. The NRG chip wasn't working and I checked that the firmware version is 715. I think 723 is a the latest version and so I am trying to update the...
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...
