NINA-B41 module , notify data size is limited to around 50 bytes

Hello , I tried Integrating NINA-B41 ble module with STM32F412 series board , Ble module is communicated over uart through AT command , it is working fine

BUT When I send Data through "NOTIFY" , The Data size is limited to around 50-60 bytes , the data sheet shows it may support till 247 bytes , but i am unable to receive that much bytes when send from STM32 through NINA-B41 module to an nrf Connect App.

I am using nrf Connect App to communicate to my STM device.

Careful: Those modules are programmable, and we have no idea what program these use here. It is possible that you are limited by the module firmware.

The UART peripherial on the NRF52x chips has tiny FIFOs - using handshake linkes (RTS/CTS) strongly recommended for any baud rate above 9600 baud.

Hi Turbo J I am using a baud rate of 115200 . Also any way  can we find whether the ble module is truncating the data that is send as notify using AT commands.
