How to read/write data via BLE in Mbed OS 6?

Asked 2022-Mar-23 at 16:14

I have an Android smartphone and a Discovery L475VG IoT development board. I am trying send/receive data (both directions) via BLE. I have consulted a good bit of documentation (although much of it is out of date for Mbed OS 6) and I have been trying to analyze what's going on in the GattServer characteristicUpdate and characteristicWrite example codes. See here

The two example codes work for what they're supposed to demonstrate, but they seem to go about implementing reads and writes differently, or maybe I am just not following what's going on?

If it isn't obvious, I am not super familiar with the BLE stack as a whole, and particularly not the mbed implementation of it. I previously made an Arduino-based system that accomplished the same goal I'm trying to here, but I am having trouble figuring out more complicated, lower-level library that mbed provides.

The read() and write() functions, which seem like the obvious things I would need, appear to be private functions, so I assume there is more to it than that and, naturally, mbed Studio doesn't just let me call them from main().

Can someone point me in the right direction of where to start?

I tried to modify the BLE_GattServer_CharacteristicWrite to allow you to set the characteristic value after writing. This approach is completely untested since I don't have access to a mbed developer board.

QUESTION

ARM, how the content of the specified section name is not overwritten?

Asked 2021-Aug-08 at 19:27

I am working on a fw written in C++ with mbed-os for a STM32F4 series MCU. There is a portion of code that should be executed only at the first boot. To achieve this goal, the developer uses a memory section named mysection for storing a flag, named MAGIC_INIT_CODE. mysection is defined in the ARM_GCC compiler linker file under text memory. The content of mysection is written by below lines at the very beginning, just after including the headers:

this line place uint64_t object into .mysection section and initialize it to MAGIC_INIT_CODE. If .mysection is placed in flash it will be permanently there. It is being programmed when you upload your program to your micro. Ihis value will be the permanently (it cannot be changed by the standard C operations. You can only change its value by erasing the flash and programming the new value)

CAN BUS STM32 Nucleo F429ZI CAN Write Fail

Asked 2021-Jan-31 at 06:10

It is Veysel My board is STM32 Nucleo F429ZI and I use Mbed-os 6.6.0. I can read from my car CANBus data but I am not able to write on the bus. I tried it with two STM32 (same boards) and my trancivers are SN65HVD230 So I know that I can read on the CANBus , but I cannot write.

I have tried , https://os.mbed.com/users/WiredHome/notebook/can---getting-started/ with one STM32 and I have tried

for me it sounds like you forgot to drive the "RS"-pin of the CAN Transciever. This is a bit misleading in the datasheet, but it is not only "slope" control, but it also sets the Transciever to sleep. I'd recommend to use a 10k slope control resistor unlesss needed otherwise as shown here: Schematics
