Send the RPS header content of firmware file.This is a blocking API.

Parameters

[in]

rps_header

Pointer to the RPS header content.

Returns

sl_status_t. See https://docs.silabs.com/gecko-platform/4.1/common/api/group-status for details.

sl_si91x_fwup_load#

sl_status_t sl_si91x_fwup_load (uint8_t * content, uint16_t length)

Send the firmware file content.This is a blocking API.

Parameters

[in]	content	Pointer to the firmware file content.
[in]	length	Length of the content

Returns

sl_status_t. See https://docs.silabs.com/gecko-platform/4.1/common/api/group-status for details.

sl_si91x_ota_firmware_upgradation#

sl_status_t sl_si91x_ota_firmware_upgradation (sl_ip_address_t server_ip, uint16_t server_port, uint16_t chunk_number, uint16_t timeout, uint16_t tcp_retry_count, bool asynchronous)

Create an OTAF client.

Parameters

[in]	server_ip	OTAF server IP address sl_ip_address_t
[in]	server_port	OTAF server port number.
[in]	chunk_number	Firmware content request chunk number.
[in]	timeout	TCP receive packet timeout.
[in]	tcp_retry_count	TCP retransmissions count.
[in]	asynchronous	OTAF upgrade done aynchronously when this is set, else synchronous upgrade.

Initialize the client with a given configuration.

sl_net_up API needs to be called before this API.

Returns

sl_status_t. See https://docs.silabs.com/gecko-platform/4.1/common/api/group-status for details.

Note

For safe firmware upgrade via TCP server, it will take approx. 65 sec duration for upgrading the firmware of 1.5 MB file.
