As a follow on to this closed thread: UART to RS485​

What is the difference between P_UART_ISR_TX_FF_MASK and P_UART_ISR_TX_FAE_MASK ?

Do you have some example about UART callback transmission ?

We have a project using BCM20713, and we found it seems can only send 3 27 bytes packets for every connection interval. Is there any Vendor Specific Command can adjust the maximum number of packets? Thanks.

Hi, I'm using a custom board BCM20736S.

I use the UART (P32, P35) to communicate with a computer. This work fine with no problem.

But now, I would like to use an UART - RS485 convert to communicate in RS485. So I need to set and clear two IO for receive and transmit data (/RE and DE IO of a ST4385EDC for example). I have try with this code (with and without delay):

gpio_setPinOutput(GPIO_DE_RS485 / 16, GPIO_DE_RS485 % 16, CS_ASSERT);

gpio_setPinOutput(GPIO_RE_RS485 / 16, GPIO_RE_RS485 % 16, CS_ASSERT);

//bleapputils_delayUs(1000000);

puart_write('0');

puart_write('1');

puart_write('2');

puart_write('3');

//bleapputils_delayUs(1000000);

gpio_setPinOutput(GPIO_DE_RS485 / 16, GPIO_DE_RS485 % 16, CS_DEASSERT);

gpio_setPinOutput(GPIO_RE_RS485 / 16, GPIO_RE_RS485 % 16, CS_DEASSERT);

But my computer not receive the data....I think the write uart function is not executed in time...

Do you have a solution for my problem?

Thanks in advance

Hi, I'm working with a CYBLE-13025 and I would like to know which is the best way to speep up the first connection process between two devices and the reconnection after a connection down. Are there any best value to put on the ble_io_board_cfg parameters and on the blecen_cen_cfg parameters ?

Thanks

Hi,

I'm working with a CYBL£-13025 module and I would like to manage the NVRAM. I have follow some example but when I try to write some information on this memory it seems that my device get frozen and I need to reload the software on it. So is there any documentation on how to manage the NVRAM or is there any special operation to do to manage it? I'm savimìng my application on the EEPROM memory. have I to save it on the sflash memory?

thanks

Emanuele
