I am about to integrate the BLE module SPBTLE-RF which is Bluetooth v4.1. My PCB already have the footprint of the module, I just need to integrate the firmware. But I heard the Bluetooth Special Interest Group (SIG) recently announced the deprecatio...
Hi, I am Omar from Egypt. I got recently a ( STEVAL-IDB001V1 ) Kit which based on STM32L152 Discovery board.Unfortunately I didn't find any source code for the STBLC01 Bluetooth 4.0 low energy and I only found a 40 pages datasheet which doesn't has m...
As SPBTLE-RF module is already CE certified and I have its test reports also. But as a complete product we have to perform this tests again: -1) As per EMC EN 301 489-1 V1.9.2 / EN 301 489-17 standard: - a) Radiated Emission b) Electrostatic Di...
Hi,I know that RF transceiver is affected by obstacle.What's the scope of S2-LP RF transceiver with/without obstacle?Is there an analysis on S2-LP RF transceiver?Best Regards,Mohamed Amine.
Hello there,I am working on Smart Home project using BLE technology. The system needs to have a BLE mesh network to control smart switches. I wanted to use STM32F030R8 connected with SPBTLE-RF BLE chip for BLE mesh network. When I searched for the sa...
After once BLE Initialize and authentication set by fixed pairing key as "123456" then can we change again pairing key to "123678" by using this API "Aci_Gap_Set_Auth_Requirement()".Means BLE will disconnected and I will configure its authentication ...
Hello Sir / Medam,Greeting of the day.My question regarding wireless charging IC as per bellow:We want to evaluate wireless charging system for which can deliver output voltage at least 15V.So ST have any solution for it?Waiting for your quick respon...
After once BLE Initialize and authentication set by fixed pairing key as "123456" then can we change again pairing key to "123678".Means BLE will disconnected and I will configure its authentication fixed pairing key with other value during run time ...
The ST202EB (ST202EC, ST232EB, ST202EB, ...) RS232 receiver's datasheets shows the following application circuit.Table 7 lists recommended capacitors values for C2-C5 (for the device ST202E is states 0.1 nF, for device ST232 it states 1uF).I think t...
Hi everyone,(I am using TrueStudio/St-LinkV2)I am using the S2LP on a custom board. Everything worked fine (basic transmission, STack packet) until I wanted to use the auto-acknowledgment feature.Following the procedure (DS, 8.1), I have enabled AUTO...
