Posted on March 16, 2017 at 12:39In order to optimize the consumption in my project i would like to enable the dc-dc converter.The datasheet says ' Optimized results are obtained when the embedded high-efficiency DC-DC step-down converter is used.'D...
Posted on March 16, 2017 at 11:01Hi, i'm working with the BlueNRG-MS evaluation board (x-nucleo-IDB05A1) together with an stm32L073RZ.I'm putting the module in advertising mode with the stm in stop mode. With an 20ms advertising period, i am measuri...
Posted on March 13, 2017 at 11:43Hi guys,I'm using SPWF001 and wanted to write my parser since the host MCU is not STM32 (so I cant use the example). Simple question: If the module is in the middle of +WIND:xx:yyy, and I send an AT Command, is the c...
Posted on March 15, 2017 at 11:47Hello,I have a problem with the ISB027V1 Eval.Board. I have flashed and erased the Firmware and now I am looking for the File that is mentioned in the user guide WBC_FW_A11 .... but I cannot find it anywhere. Can som...
Posted on March 15, 2017 at 10:29Good afternoon~friends,it's my first time to be here.Thank you for taking time to read my post firstly. I hope I have chosen the right forum to put my troubles ! I need your help.Please give me some time to state my ...
Posted on March 15, 2017 at 01:59BlueNRG-MS is said to be compliant with Bluetooth standard. However I observed big difference in performance depending on what device connects to BlueNRG-MS. This is how it looks like: iPhone can see the advertising...
Posted on March 10, 2017 at 16:19Hi,I wanted to try using the sub-GHz radio modules; what i currently have here are 2 evaluation boards: - A IDS001V5M (SPSGRF-915 module based) - A SP1ML868 (SP1ML-868 module based)Are they compatible? Can they e...
Posted on February 24, 2017 at 14:27Hi, I'm working on the module SPSGRF-868 (868Mhz) connected to a PIC24F; the datasheet state that the maximum datarate for FSK is 500Kbps, but after a lot of test I can reach only 100Kbps with frequency dev of 3...
