Resolved! S2-LP loop antenna design
Hi,For an engineering project I've got a S2-LP and would like to use it in combination with a loop antenna. The S2-LP has a RXp and RXn output. Usually a balon is used to go from balanced to unbalanced output (50 ohm). In this case a BALF-SPI2-01D3. ...
How can I let BlueNRG-1s to sleep mode and wake-up from MFT?
Hi guys,I would the SPBTLE-1S go to sleep mode, but programming the CPU wake-up from MFT2 interrupt (leaving BLE shutdown).Do you know if it is possible do that ?If not, how can I shutdown BLE hardware leaving CPU still running?Browsing documentation...
S2LP - Trouble using both carrier sense and auto-acknowledgment
Hi all,My application needs both features. Each one is working fine one at a time. But when I enable CS feature, I cannot receive the auto-acknowledgment anymore. I got the interrupt relative to data discarded, but I can confirm (using a RTL-SDR) bot...
BlueNRG-MS pin 1.8V connected to VDD, is it a major issue? May it be corrected via software?
Hello everyone,We're currently developing a PCB using as a reference the STEVAL-WESU project, and we've accidentally tagged the pin 12 (VDD1V8) as "Blue_VDD", this is, the power supply voltage of the whole module (the same as the input provided to VB...
Using BLUEnrg2 mesh for application development and production.
I am planning to use BLE mesh in my next project. I have few questions before start designing with Blue NRG2. 1. As per the datasheet BLUENRG mesh modules are already FCC certified. I don't have to certify again right? Anyways, I am going to use appl...
Android scanning of BleNRG1 advertiser.
Hi Sir, I am working with BluenrgMS stack all things are well with ios but android BLE apps are unable to scan bluenrg devices.I have tried every solution posted in this community, but none works.why it is so only with android.
