Posted on July 06, 2017 at 01:27The BlueNRG-MS library for BLE v4.1 sets ATT_MTU to 23 bytes. Is it possible to increase this limit as long as it's less than the 255 character value length limit?I am working with the SensorTile eval board with an ST...
Hello everyone, I am experiencing a voltage issue between the IO-Link master and IO-Link devices in my new project based on IO-Link communication. The setup involves a STEVAL-IDP004V2 IO-Link master and a STEVAL-IDP003V1 IO-Link slave/device. I hav...
I bought a P-NUCLEO-IOM01M1 last week and downloaded the software from TEConcept, IO-Link Control Tool.Then I tried to connect P-NUCLEO-IOM01M1 but it was failed with an error message, MASTER_NOT_CONNECTED.I haven't changed anything on P-NUCLEO-IOM01...
I am using BLUENRG M2SA and would like to enable data length extension and increase the MTU size. I read the PM0257 programming manual and made the following changes.#define CLIENT_MAX_MTU_SIZE 185 void hci_le_connection_complete_event(uint8_t Stat...
Hi, I'm fighting with a low data throughput of the BlueNRG-MS. The BlueNRG based device acts as a peripherial and sends notifications periodicaly to PC or Android app. The problem is I'm not able to achieve a higher data rate than approx. 1 kB per se...
Hello,I'm working on a schematic where an LVDS transmitter (DS90C385AMT_NOPB) connects to a display through a connector. In my design, a 100-ohm termination resistor is placed between the differential pairs TXOUT and RXIN, as shown in the second imag...
Hello all,I have a B-L475E-IOT01A2 Discovery Kit board and need to send 250kpbs rate of data from this board to a peer device using BLE.Is this baud rate feasible with this board?
Hello, We are looking to develop an efficient battery-powered device and I wanted to know the active and the standby power consumption figure at 1.8V for the ST4SI2M0020TPIFW eSIM module. There seems to be no mention of it in the datasheet but we nee...
Hello,For a project we need to simulate PSI5 sensors.We choose the ST L9663 but it can’t send PSI5 frame. It can only be used to send PSI5 sync pulse to sensor. It can only interface master to slave.I have searched on many website but I can't find a ...
I'm trying to perform a remote firmware update, with the bluenrg-lp ota service manager, I record the manager image at the base address 0x10040000 in sequence, i can perform the update without errors via ota, but when restarting the application, i ha...
