Hello Cypress IoT team
We evaluate CYW20819 with MoodusToolBox.
We try to use "wiced_hal_puart_write" in SPP to receive callback function, and it looks like work well. In this case, it's necessary to wait until TxFIFO is empty in the callback function.
Is there any concern or time limitation about the above behavior?
Hi Yoshinori San,
There is no problem in using wiced_hal_puart_write in call back function. Please let us know if you are facing any issue , then we can figure out the cause and work around.
