Some interesting info about the effect of #spreadingfactor (#SF) in #lora #radio #mesh is in papers about SF https://pmc.ncbi.nlm.nih.gov/articles/PMC8512894 SF12 in #lora & lora https://pmc.ncbi.nlm.nih.gov/articles/PMC5038744

Can one influence the effectiveness of using multiple #rnode interfaces , in one single end-point location, with different SF by setting the #LXMF delivery limit #DELIVERY_LIMIT down https://github.com/markqvist/LXMF/blob/c426c93cc5d63a3dae18ad2264b1299a7ad9e46c/LXMF/LXMRouter.py#L38 from the default 1 MB for those #rnodes, of a set, with higher SF values?
The SF12 Well in LoRaWAN: Problem and End-Device-Based Solutions

LoRaWAN has become a popular technology for the Internet of Things (IoT) device connectivity. One of the expected properties of LoRaWAN is high network scalability. However, LoRaWAN network performance may be compromised when even a relatively small ...

Can one set the #lxmf #reticulum delivery limit in #reticulum #meshchat on a per #interface basis i.e. per connected #rnode interface? https://github.com/markqvist/LXMF/blob/c426c93cc5d63a3dae18ad2264b1299a7ad9e46c/LXMF/LXMRouter.py#L38
#deliverylimit #DELIVERY_LIMIT
This might help stop #lora #radio channel blocking in case one #rnode of a set of #rnodes at one end-point device use a high #spreadingfactor #sf #lorachannelblocking

It seems to be possible to set a message size delivery limit as defined by the parameter lxmf_delivery_transfer_limit_in_bytes

Setting a decent #deliverylimit in #reticulum #meshchat for an #rnode interface that matches a given radio parameter set (or sets) (#spreadingfactor #sf etc.) helps avoid the sad scenario that an rnode uses up its 10% maximum legally permitted #dutycycle allowance for that #radio #ismband when trying to send or resend payloads that stand no chance of 100% delivery in a reasonable time frame. https://loramesh.org/SF
