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...
Posted on February 23, 2017 at 13:00Hi ST,I am working with the BlueNRG-1 using STEVAL_IDB and i have few questions please:1- When i program some ST BLE via using Navigatorv2.3.0, the main code not the BLE stack, where it saved? in the main MCU or t...
Posted on May 17, 2016 at 05:24Hi, When the chip is initiated with GAP_INIT, it automatically creates a device name and appearance characteristics. Those are created with write properties, allowing anyone to rewrite the name of the device. I don't f...
Posted on March 03, 2017 at 01:17I am getting an error when calling the stack initialization function but can not find an explanation of the return code in any of the ST documentation.The value I see is 0x0c.Thanks,Keith#bluenrg-1 #ble
Posted on February 13, 2017 at 19:28Hi,I'm experiencing stoppages with a STM32 connected to an BLUENGR.After set adverttising successfully, sometimes BLUENGR stops advertising. If I force a new aci_gap_set_discoverable, I get 0xff as response (when ...
Posted on March 03, 2017 at 23:47I have chip on which there's (probably) SP01 P511 (Picture attached). It was manufactured by ST. Probably it's W-MBUS module (or RF in general). I cannot find it anywhere. Do you have datasheet for it?#rf-receiver-tr...
