[SOLVED] Uart Emulation/Terminal with STM32WB55

Hello everyone,

I would like to use the Uart over BLE with the STM32WB55.

I'm not very familiar with BLE, but as I understood for now, Uart over BLE is not a Bluetooth SIG standard, but people have been developing custom services for it.

I couldn't find any example with the STM32WB55, does any have one with that?

I'm a looking for what is called a GATT server ?

Moreover, in STM32_WPAN middleware, I could find theses UUIDs. They seem to be related with my need but I'm not sure how to use it.

/* Custom Services*/
/* UUIDs for data transfer service */
#define DATA_TRANSFER_SERVICE_UUID (0xFE80)
#define DATA_TRANSFER_TX_CHAR_UUID (0xFE81)
#define DATA_TRANSFER_RX_CHAR_UUID (0xFE82)

Best regards,

Rico

​By UART do you mean a link over BLE?

We have a project here  under STM32Cube_FW_WB_V1.4.0\STM32Cube_FW_WB_V1.4.0\Projects\P-NUCLEO-WB55.Nucleo\Applications\BLE\BLE_CableReplacement which emulates a cable connection to use as a Point-to-Point communication.

Hello Remi,

yes that's what I mean, I want to do a kind of terminal on the WB55 side, and on a smartphone be able to send custom frames.

Thank you for your answer, I'm going to see the project you mentionned, when I saw it's name I didn't understand it in that way ;)

Regards,

Eric
