Posted on October 13, 2015 at 10:31Hi,i'm using the SPWF01SA with high baud rates (460k or 920k) and continuous transmission at maximum speed. From time to time (minutes for 460k, all the time for 920k), data sent via UART is not transmitted via WIF...
Posted on April 04, 2017 at 18:56Has anybody tested long range?And willing to share results and parameters used?Also how many devices is it feasible to connect to a gateway?
Posted on April 04, 2017 at 11:46Hi,I'm currently using a bluenerg_ms module; i've managed to make it work in slave and master mode (separately), and i'm now trying to wrap my head around the master&slave simultaneous mode.What i currently do is to ...
Posted on April 04, 2017 at 12:11Hi,I'm using the BlueNrg-1 evaluation board. Built the chat application server mode.Added BlueNrg_sleep() to the main loop.Checking the current at JP4, I'm getting about 160uA-250uA current during advertising and con...
Posted on March 31, 2017 at 10:32Hi All,I am running BLE central and peripheral profile applications on Mentor Graphics Nucleus RTOS using two STM32 MCUs interfaced with BlueNRG-MS modules. BlueNRG-MS firmware version is 7.2a, STSW-BLUENRG-DK versio...
Posted on March 30, 2017 at 13:05Hi All,I have question about BLUENRG-1, can it run as stand alone without another MCU?If yes, I would appreciate very much if you could refer me to some references.Regards,Nav Dev.#bluenrg-1 #standalone-mode
Posted on March 31, 2017 at 13:29Hi All, I need to send information using the uart of my SPWF01SA wifi module. I have seen that uI need to use the signal TXD1 but i dont know if it is possible send data to this signal using http.I have made some tes...
Posted on March 30, 2017 at 18:34I am communicating with the BlueNRG-MS over SPI using an ST eval board with an F1 micro. I am able to send data over the MOSI line and receive the 0x2 ready data as shown in the attached image. I am having issues wit...
Posted on March 28, 2017 at 17:17Is it possible to connect an external eeprom to the SPWF01SA.21 module? The stored eeprom data will be very small >1K and only serve to remember GPIO high or low settings of the modules STM32F103 core that an end use...
Posted on February 24, 2017 at 07:37Hi, I am new to ST-Bluetooth. I have experience in TI LPRF and planning to do something in BlueNRG-1, because of TI background I have few questions! TI BLE stack is based on IAR/CCS IDEs, for ST stack what is the...
