URL: https://github.com/apache/mynewt-nimble/issues/1590
Hello,
I am using an STM32 (with FreeRTOS) connected through uart to an NXP
88w8987. While working on getting nimble to work I noticed that HCI commands
sent from host to controller with ble_hs_hci_cmd_send are not freed. There is a
buffer of size 1 (i.e. 1 command) so I got a crash on the second command due to
failed memory allocation.
I have modified nimble/host/src/ble_hs_hci_cmd.c like this:
ble_hs_hci_cmd_send(uint16_t opcode, uint8_t len, const void *cmddata)
{
....
ble_transport_free_cmd(cmd);
return rc;
}
and added the free-function to nimble/transport/src/transport.c:
os_error_t ble_transport_free_cmd(void * cmd) {
return os_memblock_put(&pool_cmd, cmd);
}
and now it works for me. Is the free-ing missing or am I missing something?
